What type of PR is this?

Fixes #268

Does this PR introduce a user-facing change?:

Add support for `nginx.ingress.kubernetes.io/permanent-redirect` and `nginx.ingress.kubernetes.io/temporal-redirect` + warnings for `nginx.ingress.kubernetes.io/proxy-redirect-from` and `nginx.ingress.kubernetes.io/proxy-redirect-to`

Hi @jgreeer. 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.

nginx.ingress.kubernetes.io/from-to-www-redirect, nginx.ingress.kubernetes.io/permanent-redirect-code, and nginx.ingress.kubernetes.io/temporal-redirect-code require 307/308 status code support, so they cannot be implemented until v1.5 release.

tbh gwapi 1.5 is just around the corner. I think we can merge this as is. WDYT @mikemorris

this doesn't have the 307/308 status codes, it emits warnings for them. so we can merge now and then make another PR later for the status code annotations.

+
+				// Set port if present
+				if parsedURL.Port() != "" {
+					port, err := strconv.Atoi(parsedURL.Port())


Why are we ignoring this error? Let's append to errs.

This did get me thinking... we could have named ports here right?

this does gets caught by url.Parse() before we reach this, but i added a check to be safe. also not sure what you mean steven?

@jgreeer i just reread this and what I said makes no sense

@jgreeer Atoi can only really fail if the port overflows int, which shouldn't be possible unless you are actively trying to mess up. This seems fine.
