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

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`.

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.

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.

According to #1216, we need to simply the code by removing the
support of anything before Jewel.

* changed s/colocation/collocation/
* declare dmcrypt variable in ceph-common so the variables check does
not fail

This is purely a refactor. Converts when 'and' conditionals into lists
rather than multiline strings. This does not work for nested
conditionals, but those can be formated with indents.
Moves one line when statements onto the same line as the when command
itself.
A small logic bug was found in ceph-osd/tasks/check_devices.yml which
which was also fixed.

The ceph-osd role currently uses ansible_service_mgr, which is a fact
only available on ansible 2.x and greater. This commit sets a similar
fact called init_system which will store the contents of /proc/1/comm
(systemd, init, etc.) and then references it ceph-osd instead.
Closes#741
we now have the ability to enable the `cluster` variable with a specific
value that will determine the name of the cluster.

With Jewel comes a new store to store Ceph object: BlueStore. Adding an
extra scenario might seem like a useless duplication however the
ultimate goal is remove the other roles later. Thus this is easier to
add new role instead of modifying existing one. Once we drop the support
for release older than Jewel we will just remove all the previous
scenario files.

When autodiscovering disks, disks can be skipped if either they are
removable, or if they have partitions on them. Skipped actions have no
'rc' attribute, though, so the 'ceph prepare' conditional fails unless
we first check to ensure that the results were not skipped before
checking the return value.
as stated in https://github.com/ansible/ansible/issues/4297
if we register a variable twice and even if a task is skipped the
register will not get overwritten... So we use the fact variant as
mentionned in the ansible issue.

While this is not widly used (AFAIK :p) the feature was broken. Thanks
to @zmc for reporting it. You can now set `osd_auto_discovery` to
true in your group_vars/osd and it will go through all the devices
available and will make them OSDs.

At the moment, all the tasks using the file module are duplicated to have differents ownerships depending on the fact `is_ceph_infernalis`.
The goal of this commit is to have a new logic for this:
- First set facts depending on the `is_ceph_infernalis` fact
- Create the files or directories using the setted facts as ownerships.
This will likely one day or another break something. If ceph-disk
complains about a disk just use the purge-cluster.yml playbook first as
it will wipe all the devices.
