X-Git-Tag: v5.0.2~22

ceph-facts: add get default crush rule from running monitor

In case of deploying new monitor node to an existing cluster,
osd_pool_default_crush_rule should be taken from running monitor because
ceph-osd role won't be run and the new monitor will have different
osd_pool_default_crush_role from other monitors.
