While running big boxes with 72 disks it's easy to get out of PID for
all the threads needed by Ceph. Increasing the default value removes
this limitation.

Depending on what we want to test, it might be handy to simply disable
the creation of a specific virtual machine. Now if NRGWS is set to 0
this will disable it.

Mostly cosmetic changes with a few changes to preferred conditional
formatting.
The only linting issues outstanding are lines that are too long and
using snake_case for the filename.
In ceph-common you load {{ ansible_managed }} at the top of the main
config file - this will trigger handlers on that file whenever an
Ansible run is made.
I'd suggest replacing it with a vanilla text comment 'managed by
Ansible' to warn
admins but avoid unnecessary cluster bounces.

The ceph.conf.j2 template currently always uses the current host facts
to get the IP address of each host in the mon loop. This is not the
expected behavior. This patch uses the correct facts to get the IP.
Recovery and/or re-balancing decrease performance, adding more options
might help tweaking this behavior.

Since 192.168.0.0/24 is very commong and might overlap with some
existing networks on your laptop, using another subnet like '42' is less
bound to happen.

Because of the following bug: http://tracker.ceph.com/issues/8551
If we use a disk file size of 1GB the OSD weight calculation ends up
being 0. Thus no data will be stored on any OSD.
Increasing the disk file size up to 11GB (we save some filesystem
overhead since the calculation is based on df thus 11GB is safer than
10GB). Because we significantly increased the size of the disk files we
now only create 2 devices per OSD host.

Proviously we used osd_crush_update_on_start: true, this was interpreted
by Ansible as a boolean and appeared as 'True' inside the Ceph configuration
file. However the Ceph's init script is looking for 'true'.

This commits introduces the support of the developpement branches of
Ceph. You can now install Ceph from master.
The behavior is done through 2 new options:
* ceph_stable: true will use the stable branch
* ceph_dev: true will use the dev branch
For the dev packages don't forget to set the branch that you want to
use.

Prior to this patch, the first match was winning and the playbook wasn't
doing any difference both "restart ceph", adding a distro filtrer fixes
this.
