[openshift-support] k8gb does not have the permissions to set the ingress name

[raffaelespazzoli]

the k8gb pod reports this error:

{"@l":"error","error":"ingresses.extensions \"roundrobin\" is invalid: spec.rules[0]: Forbidden: you do not have permission to set host fields in ingress rules","@c":"/home/runner/work/k8gb/k8gb/controllers/ingress.go:69","@t":1617380503,"@m":"Failed to create new Ingress Ingress.Namespace: k8gb-test, Ingress.Name: roundrobin"}

in order to fix this error the following permissions must be granted:

- apiGroups:
  - route.openshift.io
  resources:
  - routes/custom-host
  verbs:
  - create
  - update

it should be possible to safely grant this permissions always as it does not do anything when not running in openshift.
