This is the initial PR for tracing, which simply sets up a global TracerProvider via an init function. Subsequent tracing-related PRs can then focus solely on adding spans:

ctx, span := tracer.Start(r.Context(), "hello-span")
defer span.End()

// do some work to track with hello-span

Which issue(s) this PR fixes:
issue: #1520

Hi @Frapschen. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Just a nit for typo in logs to replace MeterProvider with TracerProvider and other LGTM. Will let @liu-cong @nirrozenbaum @ahg-g to take another review.

@JeffLuoo If the telemetry.go looks good to you, can you lgtm on that? I can lgtm on the flag and helm changes.

I have a question on the error return, left a comment

[JeffLuoo]

Just a few nits from my side. Other than that it LGTM. @liu-cong please give it another look.
