Now, the CephBlockPool CRD is managed with the controller-runtime. So the watcher is outside of the main controller reconciliation loop of CephCluster which brings numerous benefit such as: * having its own reconciliation loop * won't block anything from the main CephCluster controller loop * fast than waiting for CephCluster loop to completion Partially close: https://github.com/rook/rook/issues/1981 Signed-off-by: Sébastien Han <seb@redhat.com>
