When you delete an SMCP, all the member namespaces should be cleaned up (de-configured). The ServiceMeshMember and ServiceMeshMemberRoll status should be updated accordingly.

When this is implemented, we can remove the hack in the SMMR controller where we clear the configuredMembers array, as the full SMMR reconciliation will do the same. But we can only do this when we allow the SMMR reconcile to proceed whether the SMCP exists or not.
