Changes

https://github.com/gorilla/websocket is deprecated and unmaintained.
We should switch to something that is and ensure everything works as expected (ie. draining in queue proxy etc).
In this PR, I've replaced gorilla/websocket with gobwas/ws.

Special notes for your reviewer
Thank you for reviewing this PR.
Please let me know if I have made any mistakes or if there are any improvements that could be made.

Welcome @Gekko0114! It looks like this is your first PR to knative/pkg 🎉

[knative-prow]

Hi @Gekko0114. Thanks for your PR.

I'm waiting for a knative 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.

Hi @dprotaso,

I've created this PR for fixing this issue.
Could you have a look?
Thanks,

Are you able to create a WIP in the downstream serving repo to test the changes you've made - ie. use the go replace directive to point to your fork

[Gekko0114]

Sure. I'll do it.

Closing this for now - seems like RedHat might become owners of gorilla/websocket - so we'll pause this for now
