[chore] Add grpc instrumentation e2e test

[MikeGoldsmith]

Add e2e test for grpc instrumentation.

• Close add fixture-based e2e test for grpc instrumentation #85

[MikeGoldsmith]

I've tested the app runs and calls the grpc server. Do we know for sure grpc instrumentation is working?

No, we don't 😄 Check out #78 . That was the main drive behind wanting a test on this sooner than later. Did you create the traces.json part of the test from scratch based on the others?

Looks like the sample job is timing out in the CI failure: https://github.com/open-telemetry/opentelemetry-go-instrumentation/actions/runs/4811053910/jobs/8564536923?pr=106#step:15:5

Checking out your branch and running make fixture-grpc on my machine, the Pod logs appear to have the same error that @JamieDanielson pointed out in #78:

• [chore] Update offsets for go 1.20.4 #135

[MikeGoldsmith]

Going to wait for #150 as it resolves part of the issue I was working through. The content of the traces json still has some fixes that we'll need to resolve.

[MrAlias]

@MikeGoldsmith it looks like #150 has merged. Are you still planning to work on this?
