Code review comment for lp://staging/~ajkavanagh/charms/trusty/glance/use-assess-status-lp1531767

As the purpose of the MP is to implement assess_status() we need to make sure it runs after every hook.

Currently in glance_relations.py set_os_workload_status is called which will clobber any paused status. This should be replaced with a call to asssess_status() and as Liam points out assess_status should ultimately call set_os_workload_status.

    try:
        hooks.execute(sys.argv)
    except UnregisteredHookError as e:
        juju_log('Unknown hook {} - skipping.'.format(e))
    set_os_workload_status(CONFIGS, REQUIRED_INTERFACES,
