shill: Notify upstart when shill is offline
Add an Upstart proxy, which can ask the upstart process to emit
events. Invoke this event whenever the shill manager becomes
idle.
BUG=chromium:447796
TEST=Unit tests + manual:
Create a dummy "offline.conf" file in /etc/init which starts
with "start on shill-disconnected", and ensure that this script
is invoked if we disconnect the network.
