History
Serge van Ginderachter b878370a0b Add Ceph/RBD support to playbooks 
Currently the playbooks do not allow Ceph to be configured as a backend
for Cinder, Glance or Nova. This commit adds a new role called
ceph_client to do the required configuration of the hosts and updates
the service roles to include the required configuration file changes.
This commit requires that a Ceph cluster already exists and does not
make any changes to that cluster.

ceph_client role, run on the OpenStack service hosts
  - configures the Ceph apt repo
  - installs any required Ceph dependencies
  - copies the ceph.conf file and appropriate keyring file to /etc/ceph
  - creates the necessary libvirt secrets

os_glance role
glance-api.conf will set the following variables for Ceph:
  - [DEFAULT]/show_image_direct_url
  - [glance_store]/stores
  - [glance_store]/rbd_store_pool
  - [glance_store]/rbd_store_user
  - [glance_store]/rbd_store_ceph_conf
  - [glance_store]/rbd_store_chunk_size

os_nova role
nova.conf will set the following variables for Ceph:
  - [libvirt]/rbd_user
  - [libvirt]/rbd_secret_uuid
  - [libvirt]/images_type
  - [libvirt]/images_rbd_pool
  - [libvirt]/images_rbd_ceph_conf
  - [libvirt]/inject_password
  - [libvirt]/inject_key
  - [libvirt]/inject_partition
  - [libvirt]/live_migration_flag

os_cinder is not updated because ceph is defined as a backend and that
is generated from a dictionary of the config, for an example backend
config, see etc/openstack_deploy/openstack_user_config.yml.example

pw-token-gen.py is updated so that variables ending in uuid are assigned
a UUID.
