We have a scenario when we switch from non-container to containers. This
means we don't know anything about the ceph partitions associated to an
OSD. Normally in a containerized context we have files containing the
preparation sequence. From these files we can get the capabilities of
each OSD. As a last resort we use a ceph-disk call inside a dummy bash
container to discover the ceph journal on the current osd.

The name docker_version is very generic and is also used by other
roles. As a result, there may be name conflicts. To avoid this a
ceph_ prefix should be used for this fact. Since it is an internal
fact renaming is not a problem.
Add the variables ceph_osd_docker_cpuset_cpus and
ceph_osd_docker_cpuset_mems, so that a user may specify
the CPUs and memory nodes of NUMA systems on which OSD
containers are run.
Provides a example in osds.yaml.sample to guide user
based on sample `lscpu` output since cpuset-mems refers
to the memory by NUMA node only while cpuset-cpus can
refer to individual vCPUs within a NUMA node.
there is no need to have a condition on this task, this test should be
always run since the result will be interpreted later.

During the initial implementation of this 'old' thing we were falling
into this issue without noticing
https://github.com/moby/moby/issues/30341 and where blindly using --rm,
now this is fixed the prepare container disappears and thus activation
fail.
I'm fixing this for old jewel images.
Also this fixes the machine reboot case where the docker logs are
purgend. In the old scenario, we now store the log locally in the same
directory as the ceph-osd-run.sh script.

Use "ceph_tcmalloc_max_total_thread_cache" to set the
TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES value inside /etc/default/ceph for
Debian installs, or /etc/sysconfig/ceph for Red Hat/CentOS installs.
By default this is set to 0, so the default package value will be used,
if specified this value will be changed to match the variable, and ceph
osd services will be restarted.
There was a huge resync from luminous to jewel in ceph-docker:
https://github.com/ceph/ceph-docker/pull/797
This change brought a new handy function to discover partitions tight to
an OSD. This function doesn't exist in the old image so the
ceph-osd-run.sh script breaks when trying to deploy Jewel OSD with that
old Jewel image version.

This will solve the following issue when starting docker containers on ubuntu:
invalid argument "1\u00a0" for --cpus=1 : failed to parse 1 as a rational number

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.
Here is the log for dmcrypt:

It's sad but we can not rely on the prepare container anymore since the
log are flushed after reboot. So inpecting the container does not return
anything.
Now, instead we use a ephemeral container to look up for the
journal/block.db/block.wal (depending if filestore or bluestore) and
build the activate command accordingly.

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-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.

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
