After restarting each OSD, restart_osd_daemon.sh checks that the
cluster is in a good state before moving on to the next one. One of
the checks it does is that the number of pgs in the state
"active+clean" is equal to the total number of pgs in the cluster.
On large clusters (e.g. we have 173,696 pgs), it is likely that at
least one pg will be scrubbing and/or deep-scrubbing at any one
time. These pgs are in state "active+clean+scrubbing" or
"active+clean+scrubbing+deep", so the script was erroneously not
including them in the "good" count. Similar concerns apply to
"active+clean+snaptrim" and "active+clean+snaptrim_wait".
Fix this by considering as good any pg whose state contains
active+clean. Do this as an integer comparison to num_pgs in pgmap.
(could this be backported to at least stable-3.0 please?)

Previously RETRIES was set (by default to 40) once at the start of the
script; this meant that it would only ever wait for up to 40 lots of
30s across *all* the OSDs on a host before bombing out. In fact, we
want to be prepared to wait for the same amount of time after each OSD
restart for the clusters' pgs to be happy again before continuing.

deployment.
restart_osd_daemon.sh is used to discover and restart all OSDs on a
host. To do it the scripts loops the list of ceph-osd@ services in the
system. This commit fixes bug in the regular expression responsile for
extraction of OSDs - prior version uses `[0-9]{1,2}` expression
which is ignoring all OSDS which numbers are greater than 99 (thus
longer than 2 digits). Fix removed upper limit of digits in the number.
This problem existed in two places in the script.

Extra space in systemctl list-units can cause restart_osd_daemon.sh to
fail
It looks like if you have more services enabled in the node space
between "loaded" and "active" get more space as compared to one space
given in command the command[1].

Useful for softwares that do data collection/monitoring like collectd.
They can connect to the socket and then retrieve information.
Even though the sockets are exposed now, I'm keeping the docker exec to
check the socket, this will allow newer version of ceph-ansible to work
with older versions.

If OSDs don't restart normally we now also dump info of the crush map,
crush rules, crush tree and pools.
If the monitors don't restart normally we also print the socket status
by calling mon_status and quorum_status.

Use default delay since the mon (in particular) can take more time to
restart.
Solves error with:
STDERR:
Error response from daemon: No such container: ceph-mon-mon0

This commit eases the use of the
infrastructure-playbooks/switch-from-non-containerized-to-containerized-ceph-daemons.yml
playbook. We basically run it with a couple of pre-tasks and then we let
the playbook run the docker roles.
It obviously expect to have proper variables configured in order to
work.
