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.

* Fix the label encoder as label exporter thinko

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
