From Josh Durgin, "I'd recommend not setting vfs_cache_pressure in
ceph-ansible. The syncfs issue is still there, and has caused real
problems in the past, whereas there hasn't been good data showing lower
vfs_cache_pressure is very helpful - the only cases I'm aware of have
shown it makes little difference to performance."

Install package from official repos rather than pip when using RHEL.
This commit fix https://bugzilla.redhat.com/show_bug.cgi?id=1420855
Also this commit Refact all `roles/ceph-*/tasks/docker/pre_requisite.yml`
to avoid a lot of duplicated code.

This was needed for Hammer and older version, not needed anymore since
we have a 'ceph' user to run ceph processes.

Check if ceph filesystem already exists before creating it.
If the ceph filesystem doesn't exist, execute the task only on one node.

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.

As of Infernalis, the Ceph daemons run as an unprivileged "ceph" UID,
and this is by design.
Commit f19b765 altered the default
civetweb port from 80 to 8080 with a comment in the commit log about
"until this gets solved"
Remove the comment about permissions on Infernalis, because this is
always going to be the case on the Ceph versions we support, and it
is just confusing.
If users want to expose civetweb to s3 clients using privileged TCP
ports, they can redirect traffic with iptables, or use a reverse proxy
application like HAproxy.

This avoids a situation where during a rolling_update we try to talk to
a mon to get the fsid and if that mon is down the playbook hangs
indefinitely.

This gives us more flexibility than installing the ceph-release package
as we can easily use different mirrors. Also, I noticed an issue when
upgrading from jewel -> kraken as the ceph-release package for those
releases both have the same version number and yum doesn't know to
update anything.

To configure kernel the task is using "command" module which is not
respect operator ">". So this task just print to "stdout": "never >

Some playbooks use [0-9]*, others use \d+$
The latter is more correct since cluster name may contain numbers.

Fix: #1300

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

We shouldn't test directly the value of
`ceph_conf_overrides.global.osd_pool_default_pg_num` because this can
cause the playbook to fail if the key `global` is not present in
`ceph_conf_overrides`. Therefore we have to use the facts that have been
defined earlier.

Some users purge their environments and leave it in a non-optimal state.
e.g: packages are still installed but /etc/ceph and /var/lib/ceph don't
exist anymore. This will result in multiple failures across the play,
sometimes hard to detect. Populating these directories "just in case"
should help us solving these problems.
