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 8567609b7e kv scenario: add KV_PORT option
This option was missing for rrgw, mds, rbd mirror and nfs making these
daemon impossible to run on a kv deployment with containers.

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.

Ivan Font 8c67689d08 Add option to enable ntp
This fixes #845 for containerized deployments. We now also mount the
/etc/localtime volume in the containers in order to synchronize the host
timezone with the container timezone.
