[WIP] Separate crds

[aliok]

JIRA: https://issues.redhat.com/browse/SRVKE-292

Done:

• Separate CRDs
  • Channel
  • Source --> nothing in it as it simply creates the controller for the source

TODO:

• OLM metadata
• YAML artifacts to be separated by changing the scripts here
  • https://raw.githubusercontent.com/openshift/knative-eventing-contrib/release-v${CURRENT_VERSION}/openshift/release/knative-eventing-kafka-channel-v${CURRENT_VERSION}.yaml
  • https://raw.githubusercontent.com/openshift/knative-eventing-contrib/release-v${CURRENT_VERSION}/openshift/release/knative-eventing-kafka-source-v${CURRENT_VERSION}.yaml
• Update operator version and upgrade to latest Knative version
• Hide old CRD in CSV (as marking it internal, similar to this)
• Clarify if SCC related things are necessary
• Verification instructions
• Kafka webhook SA is missing some list RBAC permissions, not sure if it is related to my changes
• Any migration docs necessary?
• Test on Minikube
• Test on OpenShift
• Stateful set watch?
• Mark CRDs as internal-objects. See hide the KnativeEventings APIs knative-eventing-operator#99

I like what I see, with the separated APIs/CRDs

Note, when we update the CSV, for the owned CRDs, let's also mark both as internal-objects, so that they are not visilbe in the developer console (only admins will see them).
