Background: In a scenario where a malformed custom Quay Config Bundle was attached to the QuayRegistry object, the Quay pods kept crash looping because they weren't able to find specific settings. In this situation the Operator remains in "MigrationsInProcess" state which will never finish.

Expected results: The Operator recognizes if deployments are failing and report that in the status block. This is probably covered by: PROJQUAY-1609
