`+` is more idiomatic for "one or more" in a regex than `{1,}`; the
latter was introduced in a previous fix for an incorrect `{1,2}`
restriction.

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.

Since the container now simply reads the ceph.conf, we remove all the
unnecessary options.
Also this PR is the foundation to support multiple backend, such as the
new 'beast' from Ceph Mimic.

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.

This commit ensures we are backward compatible with fqdn deployments.
Since ceph-container enforces deployment to be done with shortname, we
must keep backward compatibility with clusters already deployed with
fqdn configuration

Depending on your setup, ceph-mgr might get restarted multiple times.
When this is done to fast, systemd will prevent further restarts because of
configured limits in the ceph-mgr systemd unit file.
Resetting the failure count will prevent this problem. The reset is done before
the restart so in case of a real problem during the restart it still fails.

We now have the ability to deploy a containerized version of ceph-iscsi.
The result is similar to the non-containerized version, you simply have
3 containers running for the following services:
* rbd-target-api
* rbd-target-gw
* tcmu-runner

Extra space in systemctl list-units can cause restart_osd_daemon.sh to

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

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.

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.

If a deployer uses an interface name with a dash/hyphen in it, such
as 'br-storage' for the monitor_interface group_var, the ceph.conf.j2
template fails to find the right facts. It looks for
'ansible_br-storage' but only 'ansible_br_storage' exists.
This patch converts the interface name to underscores when the
template does the fact lookup.
Like 80d32dec, the path to the fact is not correct.
In any case, we will retrieve the IP address in hostvars, the variable
is the way we get the interface name according where it has been set
(eg.: inventory host file vs. group_vars/)

stable-3.0 brought numerous changes in ceph-ansible variables, this PR
aims to maintain backward compatibility for someone running stable-2.2
upgrading to stable-3.0 but keeps its groups_vars untouched.
We will then determine the right options to make sure the upgrade works
but we are expecting that new variables should be used.
We will drop this in a near future, maybe 3.1 or 3.2.

The way we handle the restart for both mds and rgw is not ideal, it will
try to restart the daemon on the host that don't run the daemon,
resulting in a service file being created (see bug description).
Now we restart each daemon precisely and in a serialized fashion.
Note: the current implementation does NOT support multiple mds or rgw on
the same node.

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.
