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.
Fixes: #14

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.

While trying to auto-provision with vagrant, new disks get /dev/sdb and
so forth. So starting from /dev/sdd doesn't make sense.

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.

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.
