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.

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.

This commit introduces a new config option 'osd crush chooseleaf type'.
With the help of this option and by setting it to '0' we tell Ceph to
store all the replicas on a single host. Basically we tell CRUSH to
iterate over disk and not over host.

since we're now using fsid for the directory name, it should be safe to
just copy the keys from all mon hosts. Once they are copied, the rest of
the hosts will just skip copying. :)
The mon_initial_members is not used since we declare the mon section in
the ceph.conf file. Later, we could reduce the ceph.conf file by only
using the mon_host flag instead of all the mon sections.

We introduced a key generation mechanism that aimed to ease deployment.
In the end, it brought more complexity to the playbook and doesn't
scale.
Reverting the auto generation commit and instructing users to generate
their own keys.

Currently everything lives in main.yml, the file has become difficult to
read at some point and can be a real mess since we keep adding new
scenarios.
I think we should separate the scenarios into dedicated files and just
do includes in the main.yml file.

As mentionned in the issue 24 it's not really safe to store a default
fsid nor a monitor key. Thus the commit brings the auto-generation of
the initial monitor key. However it is quite complex to do the same for
the fsid, so I leave this to the person in charge of the deployment to
generate one and edit group_vars/all accordingly. The default fsid has
been removed as well.

Even if MDS are not configured in site.yml the playbook has a
dependancy on the ceph.conf template.
This disables the mds section from the ceph.conf file.

Now the playbook is able to install Ceph on RedHat systems.
This has been tested on CentOS 6.

This commits brings the support of multiple journals where each journal
points to a specific OSD and vice-versa. The commit also clarifies the
usage of multi scenarios for both journal and osd_data.
In the meantime, it fixes the collocation scenario.

This brings the support of heterogeneous hardware. Not all the servers
are identical, some have more or less disks than the others. Prior this
commit, the 'parted' command was hanging, now the command simply exits 1
if the device doesn't exist, same for the 'egrep' piped command after.
Then we skip these errors and continue to run. So now, you can specify
multiple devices in group_vars/osds that don't exist on all the
servers.

Since the fetch module takes care of the permissions it is not necessary
to set them with another module. The second command is useless.
