ingressclass is hardcoded to nginx

[asteven]

Describe the bug
The created ingress resource is annotated with: "kubernetes.io/ingress.class: nginx".
I use traefik, not nginx. The nexus-operator is unusable with a non-nginx ingress.

To Reproduce
Steps to reproduce the behavior:

1. Create an nexus instance with networking.exposeAs: Ingress
2. See that the ingress is created with a annotation: "kubernetes.io/ingress.class: nginx"

Expected behavior
Ingress should be created without any annotation. It is up to the cluster operator to set the desired default ingress.class. If needed a custom ingress can be set via a custom annotation or allow setting the spec.ingressClassName somehow.

Environment
Behaves the same no matter what the env is.

Can you create the Nexus instance without the Ingress and manually create yours as a workaround?

[asteven]

Sure. That's what I'm doing.
I configure my nexus instance with networking.expose=false and create an ingress with a different name myself.
If my custom ingress has the same name as the nexus instance your operator deletes it.

[ricardozanini]

Hmm, this is a bug, should not delete it if it's not owned by the operator. Many thanks for reporting it.
