Increase kernel.pid_max to a higher value
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.

Make RGW configurable in Vagrant
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.

Remove ansible managed header from ceph.conf
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.

Fix the mon.* generation in ceph.conf
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.

Use a very unlikely subnet address for Vagrant
Since 192.168.0.0/24 is very commong and might overlap with some

Fix OSD weight and device size
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.

Add developement packages support
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

Ability to use a directory for OSD instead of a disk
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.
