Add proxy support

[krmodelski]

Similar to 2091, but for the release-1.x branch. I did not add tests this time because I had some troubles with copying agent options in the applyToHTTPSOptions method. I might work on tests in the meantime. I am using different library for HTTP/HTTPS due to this issue in previous library.

Some comments.

Given that there seems to be a typo/reverse bug in the code, I think we should really figure out how to get unit tests on this.

[cjihrig]

I agree that we should not land this without tests - particularly if most future development is intended to target this branch.

Thanks for addressing the nits. At this point, are you able to add tests?

I think I can do it.

exec doesn't seem to work 🤔 should'nt the config#applyToHTTPSOptions method be changed as well?

@CGNonofr thanks for heads-up, I will take a look at it.

[krmodelski]

@CGNonofr I added agent to applyToHTTPSOptions and tested exec. Could you please confirm it works?

Looks good!

[brendandburns]

This looks good to me, thanks for adding tests.

@cjihrig I'll leave it to you to give the final lgtm+approve.

Thanks for the contribution.

I don't think I can merge this yet. I think #2124 needs to land first.

@krmodelski it looks like there are some issues with the test here - https://github.com/kubernetes-client/javascript/actions/runs/12439738691/job/34734042786:

> tsc --project tsconfig-with-tests.json && cp 'src/test/echo space.js' dist/test

I think this wasn't caught initially because the PR branch didn't include the new checks for the tests and transpiled code.

Are you able to take a look?
