ceph: child controller-runtime stop watching for deployment

The bump from 0.2 to 0.4 controller-runtime versions which happened
during the use of Go Modules (bumping Go version to 1.13) introduced an
issue where the deployment annotations keep getting changed during
watch update event.
The easy fix is to stop watching Deployment objects for now.
