This scenario will create OSDs using ceph-volume and is only available
in ceph releases greater than Luminous.

There is only two main scenarios now:
* collocated: everything remains on the same device:
- data, db, wal for bluestore
- data and journal for filestore
* non-collocated: dedicated device for some of the component

ceph-disk is responsable for enabling the unit file if needed. Actually
since https://github.com/ceph/ceph/pull/12241 it seems that it's not
even needed. On an event of a restart, udev rules will be trigger and
they will ceph-disk activate the device too so the 'enabled' is not
needed.

We have multiple issues with ceph-disk's cli with bluestore and Ceph
releases. This is mainly due to cli changes with Luminous. Luminous
introduced a --bluestore and --filestore options which respectively does
not exist on releases older than Luminous. The default store being
bluestore on Luminous, simply checking for the store is not enough so we
have to build a specific command line for ceph-disk depending on the
Ceph version we are running and the desired osd_store.

In Luminous, ceph-disk defaults to bluestore so all our scenarios are
using bluestore, we need to force testing both.

This commits refactors how we deploy bluestore. We have existing
scenarios that we don't want to change too much. This commits eases the
user experience by now changing the way you use scenarios. Bluestore is
just a different interface to store objects but the scenarios more or
less remain the same.
If you set osd_objectstore == 'bluestore' along with
journal_collocation: true, you will get an OSD running bluestore with DB
and WAL partitions on the same device.
If you set osd_objectstore == 'bluestore' along with
raw_multi_journal: true, you will get an OSD running bluestore with a
dedicated drive for the rocksdb DB, then the remaining
drives (used with 'devices') will have WAL and DATA collocated.
If you set osd_objectstore == 'bluestore' along with
raw_multi_journal: true and declare bluestore_wal_devices you will get
an OSD running bluestore with a dedicated drive for rocksdb db, a
dedicated drive partition for rocksdb WAL and a dedicated drive for
DATA.

There is no need for 2 variables to enable bluestore, prior to this
patch one had to do the following to activate bluestore:
osd_objectstore: bluestore
bluestore: true
Now you just need to set `osd_objectstore: bluestore`.

Followup on https://github.com/ceph/ceph-ansible/pull/1469 where we
merged most of the container code from roles/ceph-*/task/docker/*.yml
into roles/ceph-docker-common/tasks/
It seems that we forgot to remove the original files.

`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.

Proof-of-concept clusters or actual production clusters will never want to use this. We also do not test it anywhere for this same reason.

Ansible's assemble module by default will put all files in the src
directory together into dest. We only want to put {{ cluster }}.conf
and osd.conf together, not anything that might have found its way into
/etc/ceph/ceph.d (e.g. files left by the sysadmin taking backups
before an ansible run). So specify a regexp that matches only those
two files.

As reported in
https://github.com/ceph/ceph-ansible/issues/1403 when devices are held
by lvm and `osd_auto_discovery` is set to true, it's not enough to check
for a partition count = 0 since Ansible does not report.
This patch also looks for 'holders' which in a case of lvm corresponds
to the name of the pv. Now we also look for holders = 0.

Problem: too many different commands to do the same thing. The 'cut'
command on infrastructure-playbooks/purge-cluster.yml was also wrong.
This sed command from osixia in ceph-docker

scenarios.

Since distro will not allow /usr/share to be writable (e.g: atomic) so
we let the operator decide where to put that script.

Oh yeah! This patch adds more fine grained control on how we run the
activation osd container. We now use --device to give a read, write and
mknodaccess to a specific device to be consumed by Ceph. We also use
SYS_ADMIN cap to allow mount operations, ceph-disk needs to temporary
mount the osd data directory during the activation sequence.
This patch also enables the support of dedicated journal devices when
deploying ceph-docker with ceph-ansible.
Depends on https://github.com/ceph/ceph-docker/pull/478

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
