Run ingress addon on without the annotaion on the Ingress

[rubenvp8510]

Steps to reproduce the issue:

1. Execute minishift with ingress enable
2. Apply an ingress object without annotation or IngressClass field
3. Ingress controller fails with "removing ingress because of unknown ingressclass " and Ingress doesn't work at expected.

I would like to enable ingress add-on but I don't want to annotate all my ingress objects. Is there a way to enable --watch-ingress-without-class flag on the nginx ingress controller? I'm using minikube 1.23.1

Any news on this?

The nginx ingress controller is supposed to run with this flags when there is the only ingress controller available, which I think is the case of minikube. This also require to bump ingress controller versions.

I see no reason why we can't support this, if someone wants to open a PR to fix this, I'd be happy to review.

Correct me if I'm wrong but PR #12702 should address this issue. They are updating the ingress controller and adding the flag --watch-ingress-without-class=true.

@rubenvp8510 support for this should have been added in pr #12702 (as @antoniordz96 pointed out) but should then be "activated" in pr #12794 for v1 ingress api (requiring k8s version 1.19+) - please test it and report back the results, thank you!
