Rename *Provider names (#1190)
* Rename *Provider names

There is overlap in naming with MeterProviders and TracerProviders. This
is means the specification is not implemented and these types can not
exist in the same package (#1179). This makes each type and related
functions and types explicit.

Eliminate Uint64NumberKind from API (#864)
fixes #851

This includes all of the associated methods, such as
  AsUint64, AsUint64Atomic, AsUint64Ptr, CoerceToUint64, SetUint64
  SetUint64Atomic, SwapUint64, SwapUint64Atomic, AddUint64,
  AddUint64Atomic, CompamreAndSwapUint64, CompareUint64

Only significant change as a result was converting the histogram
aggregator's `count` state field into an int64 from a `metric.Number`.

With multiple values being modified for each Update(), a single mutex

* Remove StateLocker implementation and comparison benchmarks

* Remove field offset tests. No longer required with no atomics.

Increase the visibility of the api/key package (#650)
* Point to the convenience functions in api/key package

This is to increase the visibility of the api/key package through the
api/core package, otherwise developers often tend to miss the api/key
package altogether and write `core.Key(name).TYPE(value)` and complain
at the verbosity of such a construction. The api/key package would
allow them to write `key.TYPE(name, value)`.

* Use the api/key package where applicable

This transforms all the uses of `core.Key(name).TYPE(value)` to
`key.TYPE(name, value)`. This also should help increasing the

prometheus: add histogram support to exporter (#601)
This PR adds histogram support to the prometheus exporter.

- Adds a new aggregator selector that returns a histogram for `MeasureKind`.
  The selector can be constructed using `simple.NewWithHistogramMeasure`
- Adds support for histogram aggregators in prometheus collect method.

With this PR, the default selector is changed to use histograms.

In order to support the prometheus histogram, the `aggregator.Histogram`
interface is extended with the `Sum` method.

fixes #487

Kick label encoder out of sdk (#574)
* Temporarily opt-out export.Labels from label encoding stuff

* Stop passing label encoding stuff to export.Labels

* Drop label encoding stuff from SDK

* Dogstatd exporter does not need to implement label exporter anymore

* more dogstatd exporter fixes

* export labels get back to encoding stuff

in a lame way, but improvements are coming in following commits

* Get encoded labels through export.Labels

* make SDK to provide its own implementation of export.Labels

* drop dead code

* add noop label exporter

* make export simple labels immutable

* Move the default label encoder to export package

* Simplify the simple export labels a bit

* Reserve some label exporter IDs

* Document and shuffle the code a bit

* Prepare for bring the iterator benchmark test back

We can install a callback to the Batcher's process function - this is
the place where we can access the labels, and thus test the label
iterator.

* Bring back the iterator benchmarks

* Simplifications and docs

* Fix copyright to be consistent with the rest

* Fix typo

* Put reserved label encoder IDs into constants

We get fewer comments about magic numbers that way.

Encode labels once during checkpoint (#572)
The `checkpoint` function is executed in a single thread so we can do
the encoding lazily before passing the encoded version of labels to
the exporter. This is a cheap and quick way to avoid encoding the
labels on every collection interval.

Add support for Resources in the SDK (#552)
* Add support for Resources in the SDK

Add `Config` types for the push `Controller` and the `SDK`. Included
with this are helper functions to configure the `ErrorHandler` and
`Resource`.

Add a `Resource` to the Meter `Descriptor`. The choice to add the
`Resource` here (instead of say a `Record` or the `Instrument` itself)
was motivated by the definition of the `Descriptor` as the way to
uniquely describe a metric instrument.

Update the push `Controller` and default `SDK` to pass down their configured
`Resource` from instantiation to the metric instruments.

* Update New SDK constructor documentation

* Change NewDescriptor constructor to take opts

Add DescriptorConfig and DescriptorOption to configure the metric
Descriptor with the description, unit, keys, and resource.

Update all function calls to NewDescriptor to use new function
signature.

* Apply suggestions from code review

Co-Authored-By: Rahul Patel <rghetia@yahoo.com>

* Update and add copyright notices

* Update push controller creator func

Pass the configured ErrorHandler for the controller to the SDK.

* Update Resource integration with the SDK

Add back the Resource field to the Descriptor that was moved in the
last merge with master.

Add a resource.Provider interface.

Have the default SDK implement the new resource.Provider interface and
integrate the new interface into the newSync/newAsync workflows. Now, if
the SDK has a Resource defined it will be passed to all Descriptors
created for the instruments it creates.

* Remove nil check for metric SDK config

* Fix and add test for API Options

Add an `Equal` method to the Resource so it can be compared with
github.com/google/go-cmp/cmp.

Add additional test of the API Option unit tests to ensure WithResource
correctly sets a new resource.

* Move the resource.Provider interface to the API package

Move the interface to where it is used.

Fix spelling.

* Remove errant line

* Remove nil checks for the push controller config

* Fix check SDK implements Resourcer

* Apply suggestions from code review

Replace Ordered with an iterator in export.Labels. (#567)
* Do not expose a slice of labels in export.Record

This is really an inconvenient implementation detail leak - we may
want to store labels in a different way. Replace it with an iterator -
it does not force us to use slice of key values as a storage in the
long run.

* Add Len to LabelIterator

It may come in handy in several situations, where we don't have access
to export.Labels object, but only to the label iterator.

* Use reflect value label iterator for the fixed labels

* add reset operation to iterator

Makes my life easier when writing a benchmark. Might also be an
alternative to cloning the iterator.

* Add benchmarks for iterators

* Add import comment

* Add clone operation to label iterator

* Move iterator tests to a separate package

* Add tests for cloning iterators

* Pass label iterator to export labels

* Use non-addressable array reflect values

By not using the value created by `reflect.New()`, but rather by
`reflect.ValueOf()`, we get a non-addressable array in the value,
which does not infer an allocation cost when getting an element from
the array.

* Drop zero iterator

This can be substituted by a reflect value iterator that goes over a
value with a zero-sized array.

* Add a simple iterator that implements label iterator

In the long run this will completely replace the LabelIterator
interface.

* Replace reflect value iterator with simple iterator

* Pass label storage to new export labels, not label iterator

* Drop label iterator interface, rename storage iterator to label iterator

* Drop clone operation from iterator

It's a leftover from interface times and now it's pointless - the
iterator is a simple struct, so cloning it is a simple copy.

* Drop Reset from label iterator

The sole existence of Reset was actually for benchmarking convenience.
Now we can just copy the iterator cheaply, so a need for Reset is no
more.

* Drop noop iterator tests

* Move back iterator tests to export package

* Eagerly get the reflect value of ordered labels

So we won't get into problems when several goroutines want to iterate
the same labels at the same time. Not sure if this would be a big
deal, since every goroutine would compute the same reflect.Value, but
concurrent write to the same memory is bad anyway. And it doesn't cost
us any extra allocations anyway.

* Replace NewSliceLabelIterator() with a method of LabelSlice

* Add some documentation

* Documentation fixes

message when they are not equal, not some uint64 representation. This
also uses InDelta for comparing floats.

So the tests can be reproducible - iterating a map made the order of
measurements random.

Rename the exporter directory to exporters (#502)
The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was
mistakenly released with a `v1.0.0` tag instead of `v0.1.0`. This
resulted in all subsequent releases not becoming the default latest,
meaning that `go get`s pulled in the incompatible `v0.1.0` release of
that package when pulling in more recent packages from other otel
packages. Renaming the `exporter` directory to `exporters` fixes this
issue by consequentially renaming the package.

Additionally, this action also renames *all* exporters. This is
understood to be a disruptive action to existing users as they will need
to update any dependencies they currently have on our exporters.
However, it was decided to take this action regardless. The need to
resolve the existing issue explained above is highly important, and
given the Alpha state of this project these kinds of breaking changes
should be expected (though not without reason).

Resolves #331

* Add comments on needed filed alignment

Add comment about alignment requirements to all struct fields who's
values are passed to 64-bit atomic operations.

Update any struct's field ordering if one or more of those fields has
alignment requirements to support 64-bit atomic operations.

* Add 64-bit alignment tests

Most `struct` that have field alignment requirements are now statically
validated prior to testing. The only `struct`s not validated that have
these requirements are ones defined in tests themselves where multiple
`TestMain` functions would be needed to test them. Given the fields are
already identified with comments specifying the alignment requirements
and they are in the test themselves, this seems like an OK omission.

* Add tests for nonabsolute and varying sign values

* Implement support for NonAbsolute Measurement MaxSumCount

Previously, the MaxSumCount aggregator failed to work correctly with
negative numbers (e.g. MeasureKind Alternate()==true).

* Pass NumberKind to MaxSumCount New() function

Allows it to set the initial state (current.max) to the correct value
based on the NumberKind.

* Revert extraneous local change

* Pass full descriptor to msc New()

This is analagous to the DDSketch New() constructor

* Remember to run make precommit first

* Add tests for empty checkpoint of MaxSumCount aggregator

An empty checkpoint should have Sum() == 0, Count() == 0 and Max()
still equal to the numberKind.Minimum()

* Return ErrEmptyDataSet if no value set by the aggregator

Remove TODO from stdout exporter to ensure that if a maxsumcount or
ddsketch aggregator returns ErrEmptyDataSet from Max(), then the
entire record will be skipped by the exporter.

Added tests to ensure the exporter doesn't send any updates for
EmptyDataSet checkpoints - for both ddsketch and maxsumcount.

* Relayout Aggreggator struct to ensure int64s are 8-byte aligned

On 32-bit architectures, Go only guarantees that primitive
values are aligned to a 4 byte boundary. Atomic operations on 32-bit
machines require 8-byte alignment.

See https://github.com/golang/go/issues/599

* Addressing PR comments

The use of Minimum() for the default uninitialized Maximum value means
that in the unlikely condition that every recorded value for a measure
is equal to the same NumberKind.Minimum(), then the aggregator's Max()
will return ErrEmptyDataSet
