Update project License headers and checking (#596)
Update license header to standard format for source files missed prior.

Add license header to new source files.

Add Makefile check to test all `*.go` and `*.sh` files have a copyright
notice (or comment about them being auto-generated) within the first few
lines.

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

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

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

Add metrics support to the OTLP exporter (#544)
* Initial metrics addition to the OTLP exporter

* Fixes

Update to incorporate merged changes.
Fix lint issues.

* Add sum float64 transform unit test

* Fix static check

* Update comments

Fix malformed License header.
Add documentation for new transform functions.
Remove errant TODO.

* Fix test failures and handle ErrEmptyDataSet

Use `assert.NoError` instead of `assert.Nil` to correctly display
checked errors.

Use the result of `assert.NoError` to guard against `nil` pointer
dereferences.

Add check to skip `Record`s that return an `ErrEmptyDataSet` error and
include test to check this error is correctly returned from the
transform package.
