* Fix type error introduced in conflict resolution
* Deep clean of go.sum
Recreate go.sum for otel-collector example and OTLP exporter.
Needs to be run `GRPC_GO_RETRY=on go test .` to not fail the failing
tests because retries are not enabled by default, nor can they be
enabled programmatically.
* 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.
