Zap disk before running ceph-disk prepare
We remove all the partitions, label and re-create something clean prior
to prepare the design. This will help solving many issues with existing
disks or while scratching/deploy test environments often.

Auto generate an FSID
It has becomes really anoying to manually generate an fsid prior to the
inital bootstrap. This commit introduces a method that auto-generates an
fsid. If for whatever reasons you want to force your own fsid you can
simply edit these 3 files and override the fsid variable:

Fixing errors in rgw playbook for Trusty
- We don’t need ceph-extra for trusty
- Enable multiverse repo for access to libapache2-mod-fastcgi
- Update cache before attempting to install packages to register
multiverse repo and only refresh cache once an hour to avoid delays in
the playbook
- Add wildcard to disabling default site as on Ubuntu it is 000_default
by…default

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.
fixes: #125

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
use.

Restart Ceph service after a configuration change
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.
