This commit aims to set the default behavior to play
`ceph-docker-common` only on first node in clients group.
Currently, we play docker-common to pull container image so we can run
ceph commands in order to generate keys or create pools.
On a cluster with a large number of client nodes this can be time consuming
to proceed this way. An alternative would be to pull container image
only a first node and then copy keys on other nodes.

This commit is a workaround for
https://bugzilla.redhat.com/show_bug.cgi?id=1550977
We iterate over all nodes on each node and we delegate the facts gathering.
This is high memory consuming when having a large number of nodes in the
inventory.
That way of gathering is not necessary for clients node so we can simply
gather local facts for these nodes.

This was taken from the openshift ansible repository here:
https://github.com/leseb/openshift-ansible/tree/master/roles/installer_checkpoint
Rationale:
A complete OpenShift cluster installation is comprised of many different
components which can take 30 minutes to several hours to complete. If
the installation should fail, it could be confusing to understand at
which component the failure occurred. Additionally, it may be desired to
re-run only the component which failed instead of starting over from the
beginning. Components which came after the failed component would also
need to be run individually.
Ceph has a similar situation so we can benefit from that
callback_plugin.

This fact is already set in site-docker.yml so there's no need to check
it again in ceph-docker-common

Now by running the playbook like this:
ansible-playbook site.yml --tags='ceph_update_config'
You can only generate a ceph configuration file on the nodes.

When deploying with Ansible at large scale, the delegate_facts method
consumes a lot of memory on the host that is running Ansible. This can
cause various issues like memory exhaustion on that machine.
You can now run Ansible with "-e delegate_facts_host=False" to disable
the fact sharing.

The container deployment is serialized, adding this task as a best
effort. If docker is already present we pull the image otherwise we wait
for the role to play.

This patch changes the `when:` keys so that they have no jinja2
delimiters. This avoids Ansible warnings which could turn into
errors in a future Ansible release.
So we can later evaluate the conditions.
Also fix the variable, we are comparing ceph_release not
ceph_stable_release

we don't know ceph_stable_release before executing the role so at least
we need to run ceph-defaults and ceph-docker-common or
ceph-common.

If we don't bootstrap the mgr after the mon and the osds handler are
called, we will never be able to reach a clean state since the pgs
stats are handled by the mgr. This also happens when doing daemon
collocation.

On a container env, machines don't have any ceph binaries so we need to
use a container to run the commands.

We must mask the image so we are sure that even if the system reboots
then the OSDs won't start.
Also remove Ceph udev rules if found on the system prior to deploy
containers. If we don't do this we are exposed to conflicts between udev
rules and sytemd unit files.
Also add the CI will now test the migration from a non-containerized cluster to a
containerized cluster.

Now we can use --limit on the container deployment too. This is useful
while deploying client nodes.
e.g: ansible-playbook -i inventory -l clients site-docker.yml.sample

This will give us more flexibility and the possibility to deploy a client node
for an external ceph-cluster.

Ceph has the ability to export it's filesystem via NFS using Ganesha.
Add a ceph-nfs role that will start Ganesha and export the Ceph
filesystems.
Note that, although support is going in to export RGW via NFS, this is
not working yet.
