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.

Followup on https://github.com/ceph/ceph-ansible/pull/1469 where we

`ceph-docker-common`:
At the moment there is a lot of duplicated tasks in each
`./roles/ceph-<role>/tasks/docker/main.yml` that could be refactored in
`./roles/ceph-docker-common/tasks/main.yml`.
`*_containerized_deployment` variables:
All `*_containerized_deployment` have been refactored to a single
variable `containerized_deployment`
duplicate `cephx` variables in `group_vars/* have been removed.

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

Prior to this patch we had several ways to runs containers, we could use
ansible's docker module on some distro and on containers distros we were
using systemd. We strongly believe threating containers as services with
systemd is the right approach so this patch generalizes to all the
distros. These days most of the distros are running systemd so it's fair
assumption.

Refactor the code using 'package' module
Fix Issue #520
(However it doesn't cover all cases because some cases are not refactorable.
Ex: because of diverging packages name between distribution)
- Update rolling update playbook to support containerized deployments
for mons, osds, mdss, and rgws
- Skip checking if existing cluster is running when performing a rolling
update
- Fixed bug where we were failing to start the mds container because it
was missing the admin keyring. The admin keyring was missing because
it was not being pushed from the mon host to the ansible host due to
the keyring not being available before running the copy_configs.yml
task include file. Now we forcefully wait for the admin keyring to be
generated before continuing with the copy_configs.yml task include file
- Skip pre_requisite.yml when running on atomic host. This technically
no longer requires specifying to skip tasks containing the with_pkg tag
- Add missing variables to all.docker.sample
- Misc. cleanup

Update each role's task to use the respective role's username, image
name, and image tag to check if a container is already running. This was
causing false failures because we were not matching any running
containers and subsequently running checks.yml to check the status of
cluster files being left behind.

Docker makes it difficult to use images that are not on signed
registries. This is a problem for developers, who likely won't have
access to a registry with proper signed certificates.
This allows the ability to use any docker image on the machine running
vagrant/ansible. The way it works is that the image in question is
exported locally, then sent to each target box and imported there.

This is purely a refactor. Converts when 'and' conditionals into lists
rather than multiline strings. This does not work for nested
conditionals, but those can be formated with indents.
Moves one line when statements onto the same line as the when command
itself.

This adds a script, generate_group_vars_sample.sh, that generates
group_vars/*.sample from roles/ceph-*/defaults/main.yml to avoid
discrepancies between the sets of files. It also converts the line
endings in the various main.yml from DOS to Unix, since generating the
samples was spreading the line ending plague around to more files.
This commit allows you to set a new variable to 'true' if you want to
have ceph admin key copied over different kind of hosts such as MDS,
OSD, RGW. To enable this just set `copy_admin_key` to true.

At the moment, all the tasks using the file module are duplicated to have differents ownerships depending on the fact `is_ceph_infernalis`.
The goal of this commit is to have a new logic for this:
- First set facts depending on the `is_ceph_infernalis` fact
- Create the files or directories using the setted facts as ownerships.
I changed the argument used for starting the mds server. (pre
infernalis)
```
service ceph start mds
```
errors, while
```
service ceph start mds.$hostname
```
correctly starts the service.
I changed the mds directory ownership from ceph:cephh to root:root
again, for pre-infernalis.
And finally, add the ceph_stable_releases checks for the upstart
activation task `for or after infernalis release'.
Since we renamed the variables and removed the old 'docker' variable we
can now collocate container daemons with standard bare metal deployment.
For instance, monitors can be containerized but osds can be deployed
traditionally.

Currently, the fetch directory is created in your working directory
(where ansible is run from). We prefer to not keep any state in this
directory and would prefer to have the fetch directory configurable so
we can store it outside of our code checkout.
This commit creates a new variable in each role called
`fetch_directory` (defaulting to the previous value of 'fetch/'), and
then updates each reference to 'fetch' to use the new variable instead.
