stable-3.0 brought numerous changes in ceph-ansible variables, this PR
aims to maintain backward compatibility for someone running stable-2.2
upgrading to stable-3.0 but keeps its groups_vars untouched.
We will then determine the right options to make sure the upgrade works
but we are expecting that new variables should be used.
We will drop this in a near future, maybe 3.1 or 3.2.

3a58757 introduced an issue for Jewel deployments, since this role is
skipped, `enabled_ceph_mgr_modules.stdout` doesn't exist, therefore, it
ends up with an attribute error.
Uses `.get()` to retrieve `stdout` with a default value so it won't fail
if this attribute doesn't exist (jewel).

In Jewel, we don't use bootstrap-rbd keyring for rbd-mirror nodes, it
results with a socket path/name different according to which ceph
release you are deploying.

This commit add new osd scenarios, it aims to simplify the CI setup and
brings a better coverage on the OSD scenarios.
We decided to differentiate between filestore and bluestore, thinking
ahead when filestore won't be supported anymore.
So we now have two classes of tests:
* Filestore
* Bluestore
In each of those classes we have container and non-container.
Then for each we test the following:
* collocated
* collocated dmcrypt
* non-collocated
* non-collocated dmcrypt
* auto discovery collocated
* auto discovery collocated dmcrypt
This gives us a nice coverage and also reduces the footprint on the CI.
We are now up to 4 scenarios, each containing 6 OSD VMs.

This patch simplifies the checks and installation tasks for NTP.
Debian and Red Hat had a check for NTP's presence but would then
install NTP right afterwards anyways. In addition, there were
tasks for atomic that weren't used anywhere else in the role.
This patch also uses a dynamic include to reduce delays from
skipped tasks.
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.
We now have a variable called ceph_pools that is mandatory when
deploying a MDS.
It's a dictionnary that contains a pool name and a PG count. PG count is
mandatory and must be set, the playbook will fail otherwise.

Ansible throws warnings when using yum/dnf/rpm with the command
module:
[WARNING]: Consider using yum module rather than running yum
This patch adds the `warn: no` argument to suppress the warnings
in the Ansible output.
The `always_run` key is deprecated and being removed in Ansible 2.4.
Using it causes a warning to be displayed:
[DEPRECATION WARNING]: always_run is deprecated.
This patch changes all instances of `always_run` to use the `always`
tag, which causes the task to run each time the playbook runs.
Modern versions of Ansible can handle a list of packages passed
directly to the package modules. This patch optimizes the package
install process by passing the list of packages directly to the
module.
This is causing unknown issues when trying to start a dmcrypt container.
Basically the container is stuck at mount opening the LUKS device. This
is still unknown why this is causing trouble but we need to move
forward. Also, this doesn't seem to help in any ways to fix the race
condition we've seen.

The rbd pool is the default pool that gets created during ceph cluster
initializaiton. If we act on the rbd related operations too early, the
rbd pool does not exist yet. Move the call to perform rbd operations
to a later stage after other pools have been created.
The rbd_pool.yml playbook has all the operations related to the rbd pool.
Replace the always_run (deprecated) directive with check_mode.
Most of the ceph related tasks only need to run once. The run_once directive
executes the task on the first host.
The ceph sub-command to delete a pool is delete (not rm).
The changes submitted here were tested with this ceph version.
ceph version 0.94.9-9.el7cp (b83334e01379f267fb2f9ce729d74a0a8fa1e92c)
This upload includes these changes:
- Use the fail module (instead of assert).
- From luminous release, the rbd pool is no longer created by default.
Delete the code to create the rbd pool for luminous release
- Conform the .yml files to use the suggested syntax.
The commands are executed on the mcp nodes and I think shell ansible module
is the right one to use. The command module is used to execute commands on
remote nodes. I can make the change to use command module if that is
prefrerred.
