this commit refact the msgr2 protocol introduction.
If it's a fresh install, let's go with v2 only.
If we upgrade to nautilus, we should go with v2+v1 syntax to ensure
nothing breaks.

We do this so that the ceph-config role can most accurately
report the number of osds for the generation of the ceph.conf
file.
We don't want to use ceph-volume to determine the number of
osds because in an upgrade to nautilus ceph-volume won't be able to
accurately count osds created by ceph-disk.

As discussed in ceph/ceph#26599, beast is now the default frontend
for rados gateway with nautilus release.
Add rgw_thread_pool_size variable with 512 as default value and keep
backward compatibility with num_threads option when using civetweb.
Update radosgw_civetweb_num_threads to reflect rgw_thread_pool_size

stdout encoding based on LC_CTYPE and PYTHONIOENCODING environment
variables.
Thoses variables aren't set when using ansible.
Currently this commit breaks non containerized deployment on Ubuntu.

Currently the default crush rule value is added to the ceph config
on the mon nodes as an extra configuration applied after the template
generation via the ansible ini module.
This implies two behaviors:
1/ On each ceph-ansible run, the ceph.conf will be regenerated via
ceph-config+template and then ceph-mon+ini_file. This leads to a
non necessary daemons restart.
2/ When other ceph daemons are collocated on the monitor nodes
(like mgr or rgw), the default crush rule value will be erased by
the ceph.conf template (mon -> mgr -> rgw).
This patch adds the osd_pool_default_crush_rule config to the ceph
template and only for the monitor nodes (like crush_rules.yml).
The default crush rule id is read (if exist) from the current ceph
configuration.
The default configuration is -1 (ceph default).

Enabling msgr2 style declaration for Nautilus and above. Prior releases
will keep the right syntax.
When upgrading from Mimic to Nautilus we must maintain something in the
form of:

With this, we could have multiple rgw instances on a single host
with a single run, don't have to use rgw-standalone.yml which does not
seems able to bind ports separately.
If you want to have multiple rgw instances, just change 'radosgw_instances'
to the number you want, which defaults to 1.
Not compatible with Multi-Site yet.

This is needed for Nautilus since the ceph-create-keys script goes away.
(https://github.com/ceph/ceph/pull/21305)
Now the module if called with 'state: fetch_initial_keys' will lookup
keys generated by the monitor and write them down on the filesystem to
the right location (/etc/ceph and /var/lib/ceph/boostrap*).
This is not applicable to container since keys are generated by the
container only.

`monitor_address_block` should be read from hostvars[host] instead of
current node being played.
eg:
Let's assume we have:
```
[mons]
ceph-mon0 monitor_address=192.168.1.10
ceph-mon1 monitor_interface=eth1
ceph-mon2 monitor_address_block=192.168.1.0/24
```
the ceph.conf generation task will end up with:
```
fatal: [ceph-mon0]: FAILED! => {}
MSG:
'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:
```
{%- else -%}
{% set interface = 'ansible_' + (monitor_interface | replace('-', '_')) %}
{% if ip_version == 'ipv4' -%}
{{ hostvars[host][interface][ip_version]['address'] }}
{%- elif ip_version == 'ipv6' -%}
[{{ hostvars[host][interface][ip_version][0]['address'] }}]
{%- endif %}
{%- endif %}
```
`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'`.

For now our best guess is to count the number of devices and multiply
by osds_per_device. Ideally we'd like to run ceph-volume lvm batch
--report and get the number of OSDs that way, but currently we need
a ceph.conf in place already before we can do that. There is a tracker
ticket that would allow os to get around the need for a ceph.conf:

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.

the ceph.conf.j2 always assumes the hostname used to register the
radosgw in the servicemap is equivalent to `{{ ansible_hostname }}`
which returns the shortname form.
We need to detect which form of the hostname was used in case of already
deployed cluster and update the ceph.conf accordingly.

there is no need to have all these conditions.
for instance, assuming `mds_group_name` is set to 'mdss':
- `if groups[mds_group_name] is defined` checks if `'mdss'` is present in `{{ groups }}`
- `if {{ mds_group_name }} in group_names` checks if the current node is part
the group `'mdss'`
- `if inventory_hostname in groups.get(mds_group_name, [])` checks if
the current node is part of the group 'mdss'
The third condition is enough to cover the need of ensuring we are
running on a mds node.
