Sébastien Han 2ea7f287fa docker: simplify variable declaration
Less configuration for the user, the container inherit from the global
variables. No more container specific variables.

Sébastien Han 2fa151b9e8 container: introduce resource limitation for containers
This can be controlled via 2 options:

* ceph_$DAEMON_docker_memory_limit
* ceph_$DAEMON_docker_cpu_limit

All daemons default to 1GB for memory and 1 CPU by default.

Andy McCrae 4671b9e74e Allow ceph service systemd overrides to be specified
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

Guillaume Abrioux ddfe019342 Refact code
`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.

Sébastien Han c2f1dca823 docker: use a better method to pull images
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

Sébastien Han 2d8ac4a586 docker: only use systemd to manage containers
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.

Chris St. Pierre c4a9b1020f Generate group_vars samples automagically
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.

Sébastien Han d7c17812dd Ability to collocate bare metal and container
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.

Matt Thompson afc934d22a Make fetch directory configurable
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.

Closes issue #383
