Drop redhat service from default nodeset samples

The service requires rhel nodes to run which we
don't have upstream and so is not being tested.
Also enabling this service requires additional
vars like activationkey,token, username etc.

Also it broke some downstream jobs which running
older version of operators and using these upstream
samples.
