Is your feature request related to a problem? Please describe.

The DNS masquerading operator protects services/ingresses/gateways with its own finalizer, if they have the annotation dns.cs.sap.com/masquerade-to set. Currently if the DNSMasqueradingOperator object is removed, the dns-masquerading-operator-cop does not care about this case, and might drop the DNS masquerading operator too early (before this one has a chance to clean up all its finalizers).

Describe the solution you'd like
This operator should block/delay the deletion of DNSMasqueradingOperator objects until the actual DNS masquerading operator has properly cleaned up all finalizers it has put to services/ingresses/gateways.
