Add context-aware versions of retry.OnError and retry.OnConflict

[steve-261370]

The current util methods for retry don't take in a context. This adds in versions which do take a context and respect the context cancellation or deadline. The implementation is rather simple, since the underlying method used, wait.ExponentialBackoff already has a context-aware version, wait.ExponentialBackoffWithContext.

The documentation updates follow how the http.Request package refers to the context-aware version:

https://pkg.go.dev/net/http@go1.22.2#NewRequest

http.NewRequest refers to http.NewRequestWithContext and the latter contains the fuller documentation.

Hi @steve-261370. Thanks for your PR.

I'm waiting for a kubernetes 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/test-infra repository.
