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.

It has been reported a couple of months ago by Dan van der Ster from
CERN that updatedb was consumming 100% of CPU while parsing system's
directories. Indeed the process was parsing the OSD PG directories that
might contains billions of objects.

After a change is made on the configuration file we must restart the
Ceph services. I also added a check that verifies if a socker exists
because during the first play there are no services running. We check if
a socket exists, if not we don't try to restart the services, if it
exists we can restart them.

* Use a box that supports all providers
* Fix hdd creation so it doesn't call customize more than once
* Introduce method to create vmdks
* Add provider customization for VMware Fusion
I added a 'ceph-' prefix to all the roles related to Ceph. Since we are
about to push the roles into the Ansible Galaxy that will be easier when
we want to use these roles into a larger environement with other roles.

This commit implements a fourth scenario where we can directely use a
directory instead of a block device for the OSDs. The purpose of this
scenario is more testing-oriented. Please note that we do not check
the filesystem underneath the directory so it is really up to you to
configure this properly. Declaring more than one directory on the
same filesystem will confuse Ceph.
