Add knative crds + move knative CRs to plugin-infra

[jenniferubah]

Description

Currently, the Knative CRs (managed by Serverless Operator) are created as part of the plugin-deps. However, this should be part of the plugin-infra because there will be risks of failure when changes are made to the these CRs (by the admin) and the RHDH operator attempts reapplication/reconciliation/reversion since the plugin-deps are handled by the operator.

Which issue(s) does this PR fix or relate to

• Relates to Enable plugins dependencies for merging Orchestrator into RHDH.

PR acceptance criteria

• Knative CRs should be applied during the plugin infrastructure set up instead of afterwards.

• Tests

• Documentation

How to test changes / Special notes to the reviewer

Pull the changes, run make plugin-infra deploy IMG={IMG}
This should apply the knative CRs and create the resources after the serverless operator is ready.

LGTM.
Did you try installing the openshift-serverless operator from the console after installing RHDH?
Just to make sure there isn't any conflict between importing CRDs for knative by RHDH to the one installed by the openshift-serverless operator.

Thanks! No, I didn't test that. I will test it out and provide feedback. Good point.
