Summary: To make it easier to monitor daemons, let's store their current state (running, died, exited, or unknown) to the db. The purpose of this is to provide more information on the daemon console about the status of daemons, especially when they are running on multiple machines. This is mostly backend work, with only a few frontend changes. (It is also dependent on a change to libphutil.) These changes will make dead or stuck daemons more obvious, and will allow more work on the frontend to hide daemons (and logs) that have exited cleanly, i.e. ones we don't care about any more. Test Plan: - run db migration, check in db that all daemons were marked as exited - start up a daemon, check in db that it is marked as running - open web interface, check that daemon is listed as running - after daemon has been running for a little bit, check in db that dateModified is being updated (indicating daemon is properly sending heartbeat) - kill -9 daemon (but don't run bin/phd yet), and check that db still shows it as running - edit daemon db entry to show it as being on a different host, and backdate dateModified field by 3 minutes, and check the web ui to show that the status is unknown. - change db entry to have proper host, check in web ui that daemon status is displayed as dead. Check db to see that the status was saved. - run bin/phd stop, and see that the formerly dead daemon is now exited.
