Code review comment for lp://qastaging/~chris.macnaughton/charms/trusty/ceph/pause-resume

This is why I was saying we need to discuss this; these actions are globally scoped to the ceph cluster, rather than to a single host or OSD. I think that we probably do want to have these actions available, I'm just not sure if we want to name them something else, pause/resume_health maybe?
