Code Issues Proposed changes

Add support for application version

Browse Source 
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.

to verify the signatures on packages. Ideally, this should be an
ASCII format GPG public key including the block headers. A GPG key
id may also be used, but be aware that only insecure protocols are
available to retrieve the actual public key from a public keyserver
placing your Juju environment at risk. ppa and cloud archive keys
are securely added automtically, so sould not be provided.
