James Page cc7256b305 Add support for application version 
Juju 2.0 provides support for display of the version of
an application deployed by a charm in juju status.

Insert the os_application_version_set function into the
existing assess_status function - this gets called after
all hook executions, and periodically after that, so any
changes in package versions due to normal system updates
will also be reflected in the status output.

This review also includes a resync of charm-helpers to
pickup hookenv and contrib.openstack support for this
feature.

Ceph Storage Backend for Cinder

Overview

This charm provides a Ceph storage backend for use with the Cinder charm; this allows multiple Ceph storage clusters to be associated with a single Cinder deployment, potentially alongside other storage backends from other vendors.

To use:

juju deploy cinder
juju deploy -n 3 ceph
juju deploy cinder-ceph
juju add-relation cinder-ceph cinder
juju add-relation cinder-ceph ceph

Configuration

The cinder-ceph charm allows the replica count for the Ceph storage pool to be configured. This must be done in advance of relating to the ceph charm:

juju set cinder-ceph ceph-osd-replication-count=3
juju add-relation cinder-ceph ceph

By default, the replica count is set to 2 replicas. Increasing this value increases data resilience at the cost of consuming most real storage in the Ceph cluster.
