Move span transforms of the OTLP exporter to internal (#593)
* Move span transforms of the OTLP exporter to internal

Breakup and move functionality of the `transform_spans.go` file into
appropriate files in the `internal/transform` sub-package. This is in
preparation of using some of the overlapping functionality to implement
Resource support in the metric side of the exporter.

Adds more specific unit tests for some of the functionality transferred.
The tests removed used the exporter as a processing engine and the
replacement tests do not do this. The test found in the `oltp_test.go`
seem to comprehensively cover this type of test.

Include Link `Name` in the exporter span link and adds a test to check
for this.

Resolves #527

Pre-release script fixes (#592)
* Make pre_release.sh script work with GNU

The `-i` sed flag is for doing in-place updates of the file. On some
systems it requires a parameter, on other (GNU) the parameter is
optional, but should be "glued" to the flag (`-i.bak` for example).
That's is problematic, so just emulate the in-place updates with
copies and removals.

* Update the version string in sdk with the pre-release script

This was a missing step, which is why we still have a version string
"0.2.3" while in reality it should be "0.3.0". Hopefully it will be
something to fix in "0.3.1" or what the next release version will be.

* Ensure clean git state when doing a release

The script does `git add .` which adds everything in the tree, even
the untracked files. Make sure that there are none of those.

Encode labels once during checkpoint (#572)
The `checkpoint` function is executed in a single thread so we can do

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

Zipkin exporter (#495)
* Add zipkin exporter

The zipkin exporter implements the SpanBatcher interface. It follows
the current-at-the-time-of-writing document about conversion from
OpenTelemetry span data to Zipkin spans. Which means that endpoint
information is not yet filled.

* Fix typo in docs

* Add a zipkin example

This sends span information to a locally running zipkin collector.
Currently I have a problem getting the collector to show me the spans
after accepting them with HTTP 202. Not sure if this is because of
missing endpoint information.

* Make gitignore consistent

The fixed paths should be prefixed with a slash. The "relative" paths
mean that git will ignore all the files that end with the path.

Context propagation in opentracing bridge (#525)
* Propagate context changes in mix tests

We will need this for testing the correlation context and baggage
items propagation between the APIs.

* Add baggage interoperation tests

The test adds a baggage item to active OT span and some correlation
key value to current Otel span. Then makes sure that the OT span
contains both the baggage item and some translated version of the
correlation key value its Otel sibling got, and that the Otel span
contains both the correlation key value and the baggage item its OT
sibling got.

* Add hooks functionality to baggage propagation

This introduces two kinds of hooks into the correlation context
code.

The set hook gets called every time we set a Map in the context. The
hook receives a context with the Map and returns a new context.

The get hook gets called every time we get a Map from the context. The
hook receives the context and the map, and returns a new Map.

These hooks will be used for correlation context and baggage items
propagation between the Otel and OT APIs.

* Warn on foreign opentracing span

* fixup for using otel propagators

* Add utility function for setting up bridge and context

This prepares the context by installing the hooks, so the correlation
context and baggage items can be propagated between the APIs.

* Add bridge span constructor

So I do not need to remember about initializing a newly added member
in several places now.

* Propagate baggage across otel and OT APIs

This uses the set hook functionality to propagate correlation context
changes from Otel to OT spans by inserting keys and values into the
baggage items. The get hook functionality is used to propagate baggage
items from active OT span into the otel correlation context.

* Use correlation Map for baggage items

We will put this map into the context with correlation context
functions, and that is easier if we have correlation.Map, not
map[string]string.

* Use otel propagators in bridge

The otel propagators are now kinda sorta usable for opentracing
bridge. Some more work is needed to make it fully work, though -
correlation context set with the otel API is not propagated to OT
spans as baggage items yet.
