What Does This Do

Creates new configuration for otlp traces export mode.

Motivation

RFC: https://docs.google.com/document/d/1AsUrJxjJavLvSG33kUAJLYzGU8IYgrnf1SMbFDsuGmo/edit?pli=1&tab=t.0#heading=h.wbjhtxw8dxti

New configuration for enabled "otlp export" mode. Follow-up PRs will implement a new, otlp-conformant trace serialization mechanism if this configuration is enabled.

Additional Notes

This test seems to just be checking that the otel.env.unsupported metric is reported when an otel environment variable is discovered with an unsupported value; since this PR adds support for OTEL_TRACES_EXPORTER=otlp, I changed the test value to some other unsupported value -- "zipkin"

This method is not currently used, but will be used in a follow-up PR.

I previously had an additional method for getTraceOtelExporter, to just get the value, but I removed this as it was not currently used, and my immediate follow-up PRs will not use it.

It will only become necessary if we support the other OTEL_TRACES_EXPORTER fields in the future.
