This commit makes the playbook fetch the minimal current ceph
configuration and write it later on monitoring nodes so `cephadm` can
proceed with the adoption.
When a monitoring stack was deployed on a dedicated node, it means no
`ceph.conf` file was written, `cephadm` requires a `ceph.conf` in order
to adopt the daemon present on the node.

It has come to our attention that using ansible_* vars that are
populated with INJECT_FACTS_AS_VARS=True is not very performant. In
order to be able to support setting that to off, we need to update the
references to use ansible_facts[<thing>] instead of ansible_<thing>.

There's no reason to not use the ceph_osd_flag module to set/unset osd
flags.
Also if there's no OSD nodes in the inventory then we don't need to
execute the set/unset play.

When rerunning the cephadm-adopt.yml playbook the radosgw realm,
zonegroup and zone tasks will fail because the task isn't
idempotent.
Using the radosgw ansible modules solves that problem.

If the cephadm-adopt.yml fails during the first execution and some
daemons have already been adopted by cephadm then we can't rerun
the playbook because the old container won't exist anymore.
Error: no container with name or ID ceph-mon-xxx found: no such container
If the daemons are adopted then the old systemd unit doesn't exist anymore
so any call to that unit with systemd will fail.

The ceph status command returns a lot of information stored in variables
and/or facts which could consume resources for nothing.
When checking the quorum status, we're only using the quorum_names
structure in the ceph status output.
To optimize this, we could use the ceph quorum_status command which contains
the same needed information.
This command returns less information.
$ ceph status -f json | wc -c

The ceph status command returns a lot of information stored in variables
and/or facts which could consume resources for nothing.
When checking the pgs state, we're using the pgmap structure in the ceph
status output.
To optimize this, we could use the ceph pg stat command which contains
the same needed information.
This command returns less information (only about pgs) and is slightly
faster than the ceph status command.
$ ceph status -f json | wc -c

This is a partial revert of b38019e because we don't want to execute
the whole play on the monitor otherwise if we have some empty group
like rgws or mdss then the orchestrator commands will still be
executed.
Instead we should keep the real target group name at play level and
delegate the orchestator commands to the monitor. The whole play
will be skipped is the group is empty.
