Installing the Migration Opearator in a non "migration-opeartor" namespace fails silently and issue must be dug out of logs when installing via OLM

[eriknelson]

• 3S The ansible rollout of the operator fails and one need to dig out the reason
  from the operator pod log. Operator playbook should check deplyoment namespace
  rather than failing randomly. Not obvious from operatorhub page so likely to
  not be done correctly by customers. 1) Why openshift-migration a must? 2) Any
  way to make this clear in the UI?
