Guillaume Abrioux 51c382677d shrink-mds: use mds_to_kill_hostname instead 
When using fqdn in inventory host file, this task will fail because the
mds is registered with its shortname.

It means we must use `mds_to_kill_hostname` in this task.

Dimitri Savineau 08ac2e3034 shrink: don't use localhost node 
The ceph-facts are running on localhost so if this node is using a
different OS/release that the ceph node we can have a mismatch between
docker/podman container binary.
This commit also reduces the scope of the ceph-facts role because we only
need the container_binary tasks.

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.

Guillaume Abrioux 0ae0a9ce28 shrink-mds: do not play ceph-facts entirely 
We only need to set `container_binary`.
Let's use `tasks_from` option.
