Change upstart config so monit doesn't daemonize
Change upstart config so monit doesn't daemonize

Upstart gets very confused if:
* it starts monit, expecting it to daemonize
* the monit process gets killed (e.g. by SIGHUP) before daemonizing

To close this window, pass the -I flag to monit so it doesn't
daemonize (this flag is documented specifically as being for init purposes).
