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.

Juju 2.0 renames the environment variable JUJU_ENV_UUID
to JUJU_MODEL_UUID; use this environment variable as a
fallback if JUJU_ENV_UUID is not set to support Juju 2.0,
whilst continuing to provide support for Juju < 2.0.

Track devices that have been added to the ring and allow
devices to be added to the ring post-install (currently
only allowed within the install hook). Devices added to
the ring prior to this patch existing will be migrated
to the tracking store of devices to avoid conflicts.
