Nick Harper 88caa45854 Save daemon state to database
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.

Phabricator is a open source collection of web applications which make it easier
to write, review, and share source code. Phabricator was developed at Facebook.

This is an early release. It's pretty high-quality and usable, but under
active development so things may change quickly.
