Add STEF exporter

[tigrannajaryan]

Resolves #37352

This is the First PR done according to the requirements listed at https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/CONTRIBUTING.md#adding-new-components

I intentionally left the Config barebones. It is possible we will add more config options in the future but I don't want to do it prematurely.

Subsequent PRs will add the implementation and will clarify how it works in the README.md.

A couple of minor comments. Otherwise, LGTM

[tigrannajaryan]

@dmitryax I addressed your comments.

The "Gen CODEOWNERS" github action errors with "2025/01/22 21:42:15 codeowners members duplicate in allowlist: jerrytfleung". Any idea what this is about? I can only see one "jerrytfleung" allowlist.txt, not sure what the duplicate is about. Unclear how my change is related to this error.

@atoulme since you are listed as a codeowner of githubgen, any idea what the error message is trying to tell me? Running githubgen --skipgithub locally does not give any errors (I don't have a PAT to try without --skipgithub).

[atoulme]

@tigrannajaryan the issue reported is unrelated to your PR. A member of the allowlist has become an official member of OpenTelemetry and should be removed from the allowlist.

I will open a PR to fix. Thanks for reaching out.

Thanks @atoulme
Please let me know once it is fixed, I will rebase.

[atoulme]

You will not need to rebase for this, but I can trigger a rerun. The check-codeowners job runs by checking out the main branch of the repository. The fix is here: #37423

I will let you know of what this comes to in any case.

[atoulme]

Alright, the pull_request_target is still pointing at the old main branch, so you'll need to rebase @tigrannajaryan. If you don't get around to it, I have updated with latest main here.

Thanks @dmitryax @atoulme !
