adds a ceph-docker-common role and enables custom registry usage

This allows for ceph-ansible to use other docker registries.

Task put initial mon keyring in mon kv store from
ceph-mon/tasks/ceph_keys.yml is failing when cephx is disabled. The root
cause is that variable monitor_keyring is not populated by any task from
deploy_monitors.yml.

Fixes: #1211

in ceph-common there is a fact check for monitor name
that will set it to ansible_host or ansible_fqdn

test: add cluster name support test scenario

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.

We need to honour the cluster name that was chosen by ceph-ansible and
pass it to ceph-docker.

Once we have our first monitor up and running we need to add it to the
monitor store as a safety measure. Just in case the local file gets
deleted and you need to add a new monitor. Now you can retrieve this key
like this:

ceph config-key get initial_mon_keyring > initial_mon_keyring.txt

Just for clarity and because we can we now show the name of the
ceph configuration file that is generated.

This commit solves the situation where you lost your fetch directory and
you are running ansible against an existing cluster. Since no fetch
directory is present the file containing the initial mon keyring
doesn't exist so we are generating a new one.

We can now see the name of the file we are waiting for, depending on the
cluster name this will change.

If previous check was not run, .stdout_lines is not a valid key on the dictionary.
To get around this, use .get("stdout_lines") instead.

Also add in a default empty list

For readibility and clarity we do not run any tasks directly in the
main.yml file. This file should only contain include, which helps us
later to apply conditionnals if we want to.

This commit re-uses some of the existing ceph-ansible variables for a
containirzed deployment. There is no reasons why we should add new
variables for the containerized deployment.

Once the monitor process starts it will also trigger `ceph-create-keys`
which will collect the admin key and bootstrap keys. We used to force
this command because we were having issues on some distros like centos
7.0 and 7.1 not triggering this. This is fixed on centos 7.2 and not an
issue on ubuntu 14.04 or 16.04 so we can remove this task. If the
monitor hangs or fails to start the playbook will fail right after at
the "wait for client.admin key exists" task after 300sec.

This causes a bug when fetch_directory is not a relative path to the
playbook location.

Adding that avoids this bug:

Without that you'll get failures like:

fatal: [mon0]: FAILED! => {"failed": true, "msg": "'dict object' has no attribute 'stdout_lines'"}

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)

Carefully chosen "always_run: true" parameters for read-only tasks that
register variables. This enables --check runs (at least on deployed
clusters).

- 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

Change enabling of extras repo for CentOS to use ini_file

Users reported that pool_default_pg_num is not honoured for the default
pool 'rbd'. So now we check the pg num value for the RBD pool and if it
does not match pool_default_pg_num then we delete and recreate it.
We also make sure the pool is empty first, just in case someone changed
the value manually and didn't reflect the change in ceph-ansible.

The only issue with this patch is that the pool ID will not be 0 anymore
but more likely 1.

By overriding the openstack_pools variable introduced by this commit, the
deployer may choose not to create some of the openstack pools, or to add
new pools which were not foreseen by ceph-ansible, e.g. for a gnocchi
storage backend.

For backwards compatibility, we keep the openstack_glance_pool,
openstack_cinder_pool, openstack_nova_pool and
openstack_cinder_backup_pool variables, although the user may now choose
to specify the pools directly as dictionary literals inside the
openstack_pools list.
