Major Description
We should test OperatorHub installation method on OCP 4.
By doing this one-time task think about possible automation of this in the future.
There is HowTo install CRW using OperatorHub.
DoD: OperatorHub installation method is tested manually and followup issue for automation with possible solution is created (actual implementation will be done as part of this followup issue).
There is issue about documentation which ought to be checked as well.
