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. Change-Id: I0cef2ddc2dfc04bb6631ec61e7f890ebae94961f
