I'm investigating but we can skip the check for now.

[exporter/signalfx] Fix memory leak on shutdown (#30887)
494bdb8 
**Description:** <Describe what has changed.>
<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
`goleak` was detecting leaking goroutines in tests, this attempts to
resolve. I found what appeared to be a couple races but can't reproduce
locally so I'll run CI a few times to ensure this works as expected.

Changes in PR:
1. Add correlation client Shutdown function that blocks on the
waitgroup. This is the main fix of this PR that should fix the leaking
goroutines.
2. Re-organize the shutdown process of the apm client correlation test
suite to properly synchronize the shutting down process.
3. Fix typo
4. Add goleak checks to exporter/signalfx/internal/correlation` and
`exporter/signalfx/internal/apm/correlations`

**Link to tracking Issue:** <Issue number if applicable>
Resolves #30864
#30438

**Testing:** <Describe what testing was performed and which tests were
added.>
All existing and added tests should be passing. Since this has only
failed in CI I'm going to try to run it a few times before marking as
ready for review.

[exporter/signalfx] Fix memory leaks (#31772)
19eba68 
**Description:** <Describe what has changed.>
<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.

Changes in PR:

1. Add correlation client Shutdown function that blocks on the
waitgroup. This is the main fix of this PR that should fix the leaking
goroutines.
2. Re-organize the shutdown process of the apm client correlation test
suite to properly synchronize the shutting down process.
3. Fix typo
4. Only block request sender until context is cancelled. The request
processor is shutdown when the context is cancelled, so this would
result in `Shutdown` waiting forever, since the request would never be
processed.
5. Enable goleak in some more packages.

**Note**: This is contains the exact same contents as
#30887,
but change number 4 is new, and should resolve the test issue the
original PR was causing.

**Link to tracking Issue:**
Resolves
#30864

#30438

**Testing:** <Describe what testing was performed and which tests were
added.>
All existing tests are passing, as well as added goleak checks. I'm
going to run this a number of times to try to help ensure it's not flaky
anymore.
