Code review comment for lp:~johnsca/charms/trusty/cloudfoundry/better-basic-reconciler-status

Basically, relies on the extended hookenv.juju_status() report (which accounts for data_ready), if available, and the basic Juju status if not.

Should give us a much more accurate approximation of when the system is up, although there may still be a slight delay (due to, e.g., `monit restart all` taking some time).
