Pull request #1319 (2022-11-20 20:15:51)

Updated Gateway API from v1alpha2 to v1beta1
This introduces v1beta1 and keeps support for v1alpha2.

The e2e testes where updated to Gateway API v1beta1 and Contour v1.23.0.

Fix: #1318

Sure, IMHO I was assuming since v1alpha2 is deprecated for some months now, and Contour and GKE switched to v1beta1 that it would be okay to drop v1alpha2. I'll take a look at implementing it backwards compatible later today.
stefanprodan: @cgrotz thanks for this PR. We can't remove the Gateway API v1alpha2 and force Flagger users into upgrading right away. As with SMI, we need to keep the alpha versions around, announce the deprecation and drop support after 6 months.
cgrotz: I made it backwards compatible, but I had to create a new configuration struct for flaggerv1.

I'm also not super fond of the `var` blocks at the top of `gateway_api.go` and `gateway_api_v1beta1.go` do you have an idea how to make that nicer?
aryan9600: @cgrotz lets switch to v1beta1 in CI, could you update the contour version in the e2e tests as well?
cgrotz: @aryan9600 I changed it to v1beta1.ParentReference thanks for the idea
cgrotz: @aryan9600 the linter is still failing, I just ran go fmt again (on the whole folder and the individual files) but it doesn't change the file. What do you recommend?

aryan9600: are you sure you the command ran properly, this is what i get on my machine:
