When collocating mds on monitor node, the cephpfs will fail
because `docker_exec_cmd` is reset to `ceph-mds-monXX` which is
incorrect because we need to delegate the task on `ceph-mon-monXX`.
In addition, it wouldn't have worked since `ceph-mds-monXX` container
isn't started yet.
Moving the task earlier in the `ceph-mds` role will fix this issue.

When deploying a large number of OSD nodes it can be an issue because the
protection check [1] won't pass since it tries to create pools before all
OSDs are active.
The idea here is to move cephfs pools creation in `ceph-mds` role.

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.

This update will resolve error['cephfs' is undefined.] in multimds container deployments.
See: roles/ceph-mon/tasks/create_mds_filesystems.yml. The same last two tasks are present there, and actully need to happen in that role since "{{ cephfs }}" gets defined in
roles/ceph-mon/defaults/main.yml, and not roles/ceph-mds/defaults/main.yml.

While hostname -f will always return an hostname including its
domain part and -s without the domain part, the behavior when
no arguments are given can include or not include the domain part
depending on how the system is configured; the socket name might
not match the instance name then.
Use a nicer syntax for `local_action` tasks.
We used to have oneliner like this:
```
local_action: wait_for port=22 host={{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }} state=started delay=10 timeout=500 }}
```
The usual syntax:
```
local_action:
module: wait_for
port: 22
host: "{{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }}"
state: started
delay: 10
timeout: 500
```
is nicer and kind of way to keep consistency regarding the whole
playbook.
This also fix a potential issue about missing quotation :
```

writing `local_action: shell echo {{ fsid }} | tee {{ fetch_directory }}/ceph_cluster_uuid.conf`
can cause trouble because it's complaining with missing quotes, this fix solves this issue.

The name docker_version is very generic and is also used by other
roles. As a result, there may be name conflicts. To avoid this a
ceph_ prefix should be used for this fact. Since it is an internal
fact renaming is not a problem.
This will solve the following issue when starting docker containers on ubuntu:
invalid argument "1\u00a0" for --cpus=1 : failed to parse 1 as a rational number
Closes-bug: #2056
The `always_run` key is deprecated and being removed in Ansible 2.4.
Using it causes a warning to be displayed:
[DEPRECATION WARNING]: always_run is deprecated.
This patch changes all instances of `always_run` to use the `always`
tag, which causes the task to run each time the playbook runs.
This is to ensure `docker_exec_cmd` fact is set with the correct value
in case of daemons collocation

We generate the ceph.conf on all the nodes through the
ceph-docker-common so there is no need to push it to the Ansible file.
Also this is breaking the ceph.conf template generation since we only
generate sections based on the host the ansible task is running on.
For example, what's typically happening, we bootstrap the monitor, we
get a ceph.conf generated for a mon only, we go on an osd, we generate
the ceph.conf with osd section (done by ceph-docker-common) but this
gets overwritten by the copy_config task of the ceph-osd role.

ceph services can fail to start under certain circumstances (for
example, when running in a container) because the default systemd
service configuration causes namespace issues.
To work around this we can override the system service settings by
placing an overrides file in the ceph-<service>@.service.d directory.
This can be generic so as to allow any potential changes required to
the ceph-<service> service files.
The overrides file is only setup when the
"ceph_<service>_systemd_overrides" config_template override variable is
specified.
The available service systemd override files are as follows:
ceph_mds_systemd_overrides
ceph_mgr_systemd_overrides
ceph_mon_systemd_overrides
ceph_osd_systemd_overrides
ceph_rbd_mirror_systemd_overrides
ceph_rgw_systemd_overrides
This is under the MDS role instead of the mon role because that role
does not create the filesystem under docker.

We changed the way we declare image.
Prior to this patch we must have a "user/image:tag"
format, which is incompatible with non docker-hub registry where you
usually don't have a "user". On the docker hub a "user" is also
identified as a namespace, so for Ceph the user was "ceph".
Variables have been simplified with only:
* ceph_docker_image
* ceph_docker_image_tag
1. For docker hub images: ceph_docker_name: "ceph/daemon" will give
you the 'daemon' image of the 'ceph' user.
2. For non docker hub images: ceph_docker_name: "daemon" will simply
give you the "daemon" image.
Infrastructure playbooks have been modified as well.
The file group_vars/all.docker.yml.sample has been removed as well.
It is hard to maintain since we have to generate it manually. If
you want to configure specific variables for a specific daemon simply
edit group_vars/$DAEMON.yml
