switch: support migration when cluster is scrubbing
Similar to c13a3c3 we must allow scrubbing when running this playbook.
In cluster with a large number of PGs, it can be expected some of them
scrubbing, it's a normal operation.
Preventing from scrubbing operation force to set noscrub flag.
This commit allows to switch from non containerized to containerized
environment even while PGs are scrubbing.
'ansible.vars.hostvars.HostVarsVars object' has no attribute u'ansible_interface'
```
the reason is that it will assume `monitor_address_block` isn't defined even on
ceph-mon2 because looking for `monitor_address_block` instead of
`hostvars[host]['monitor_address_block']`, therefore it enters in the condition as default value:
`monitor_interface` is set with default value `'interface'` so the `interface`
variable is built with 'ansible_' + 'interface'. It makes ansible throwing a
confusing message about `'ansible_interface'`.
Allow user to choose between timesyncd, chronyd and ntpd
Installation will default to timesyncd since it is distributed as
part of the systemd installation for most distros.
Added note indicating NTP daemon type is not used for containerized
deployments.

restart_osd_daemon.sh.j2 - consider active+clean+* pgs as OK
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.

ceph-config: default devices and lvm_volumes when setting num_osds
This avoids errors when the osd scenario choosen does not require
setting devices or lvm_volumes. The default values for these are not
set because they exist in the ceph-osd role, not ceph-defaults.
BlueStore's cache is sized conservatively by default, so that it does
not overwhelm under-provisioned servers. The default is 1G for HDD, and
3G for SSD.
To replace the page cache, as much memory as possible should be given to
BlueStore. This is required for good performance. Since ceph-ansible
knows how much memory a host has, it can set
`bluestore cache size = max(total host memory / num OSDs on this host * safety
factor, 1G)`
Due to fragmentation and other memory use not included in bluestore's
cache, a safety factor of 0.5 for dedicated nodes and 0.2 for
hyperconverged nodes is recommended.
- Adds loop in bash to satisfy the 1:n relation between `osd_hosts` and the
different device lists.
- Fixes some container name which were using the host hostname instead
of the actual container one.
