Corey Bryant 3a5b5872c5 Add package-upgrade action
The package-upgrade action performs package upgrades for the current
OpenStack release.

The code path used is similar to the openstack-upgrade action, with the
difference being that package-upgrade will not execute if an openstack
upgrade is available (based on the openstack-origin setting).

This change includes a charm-helpers sync.
