1. Clean up when deployment is being deleted …

   Previously, when the controller is removed, it could leave a mess behind
   in the form of ConfigurationPolicy objects with finalizers on them. That
   would also result in the CRD being stuck.
   
   Now, the controller will put a finalizer on its own deployment when at
   least one ConfigurationPolicy has a finalizer. Also, while the
   deployment is being deleted, the finalizers on ConfigurationPolicies
   will be removed immediately, in the same way they would be when the CRD
   was being deleted.
   
   Note: in this implementation, related objects might *never* be pruned
   when the controller is removed.
   
   Since the controller deployment is in a different namespace than the
   ConfigutaionPolicies it watches, the controller's cache cannot be
   limited to a single namespace the way it was before. Instead, this uses
   additional cache selectors to limit watches on ConfigurationPolicies
   and Deployments to the relevant namespaces.
