refactor: remove grpc trace exporter dependency on grpc-exporter-base

[dyladan]

Todo in follow-up:

• Apply the same changes to the metrics exporter
• Remove base packages
• Pre-compile proto files to JS in order to more easily support webpack
• Possibly browser support?

@open-telemetry/javascript-maintainers there is one failing test but I actually believe the test is bad. It is asserting that if you pass metadata to the constructor, it is overridden by the environment variable. I think code should always override env config. All other tests are passing (locally at least, still waiting for CI).

Decided to keep the test for now and apply the change to all exporters at the same time later.

Just a few comments. Also a bit worried about the coverage of the security config code, as touching that code caused the exporters to break the last time around.

Brought that code over from the base package and forgot to bring the tests. good catch

[dyladan]

@pichlermarc added some tests for the security module

[pichlermarc]

Looks good. Thanks for adding the tests 🙂

lgtm but i'm not sure to understand why using the base package were breaking the exports ?

[dyladan]

@vmarchaud actually it looks like you're right. A simple test shows that the serviceClient isn't being overwritten like I thought. My initial thought was that because the onInit happened async it was being called from the super class after the child classes had already been loaded and that caused it to be overwritten but I can't reproduce it.

Going to close this since the issue was fixed in a different PR
