Bug: Rebuild deployment with incorrect annotations

Problem: When OLM checks that the Operator's Deployment was created with the correct annotations, it will not update and redeploy the operator if the annotations are incorrect.

Cause: This issue was found when creating an Operator in an OperatorGroup that uses a LabelSelector to identify namespaces in the OperatorGroup. When the operator is created, the set of namespaces returned by the LabelSelector may be different from the set of namespaces when checking the deployment annotations.

Solution: OLM should rebuild the deployment with the correct set of annotations.
