ceph: fix pool deletion when running on multus
ceph: fix pool deletion when running on multus

The ceph-block-pool controller was missing the network spec from the
cephcluster that contains all the details about networking.
So when the pool was deleting on multus the controller was not proxying
the rbd command to the mgr pod but executed the command in the operator
pod which does not have the network annotation and then connect to the
ceph cluster.
