Guillaume Abrioux 3d0898aa5d shrink-mds: fix condition on fs deletion
the new ceph status registered in `ceph_status` will report `fsmap.up` =
0 when it's the last mds given that it's done after we shrink the mds,
it means the condition is wrong. Also adding a condition so we don't try
to delete the fs if a standby node is going to rejoin the cluster.

We only need to set `container_binary`.
Let's use `tasks_from` option.
