trace exporter: using type names for return values

[moorara]

If we use type names for return values of functions, then in https://godoc.org and https://pkg.go.dev documentation the respective functions show under their types. This way, it's easier to navigate what functions are available for creating each kind of options.

I see the error message in build logs, but not sure what's the reason:

PASS
coverage: 27.5% of statements in ./...
ok  	go.opentelemetry.io/otel/exporters/otlp/internal/transform	1.037s	coverage: 27.5% of statements in ./...
FAIL
Makefile:64: recipe for target 'test-with-coverage' failed

The test is doing some shady stuff to simulate the connection dying. Looks like it's a bit flaky.
