Instead of batching based on the Resource pointer which is not guaranteed
to uniquely identify common Resources, use the `String` method which is.
Renames the external test package to be identified as the integration
testing. This testing structure (the mock exporter) batches exported
resources transmitted from the resource. This is needed as there is no
guarantees that a batch will be exported in a single payload, therefore,
it is not an ideal place to add resource batch testing for the exporter
itself.
Add unit tests to ensure the Exporter is correctly batching spans by
resource.
* Update OTLP SpanData transform
The ParentSpanId needs to be empty for root spans according to the OTLP
[docs](6c2a86ed2f/gen/go/trace/v1/trace.pb.go (L284-L286)).
This updates the SpanData transform function to not add the ParentSpanID
if it is not a valid span ID (which includes if it is the nil span ID
used for an unset ID).
Additionally, this adds a test to prevent regression.
* Simplify test to just check parent span ID transform

* 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.
