Summary:
Update the EdenFS monitor to restart itself when it receives SIGHUP. This
allows upgrading the monitor daemon to a new version of the software without
disrupting the current running EdenFS daemon.

Summary:
Update the SpawnedEdenInstance class to wait for EdenFS to become healthy
before signalling the Future returned by `start()`.
This code works by just polling the `getStatus()` call every few hundred
milliseconds, and waiting until it returns `ALIVE`.
Currently the code will poll forever, until EdenFS either becomes healthy or
exits. In practice we will likely configure startup timeouts in systemd,
which means that they probably are not necessary in this code.

Summary:
Add a simple new wrapper daemon to manage the edenfs daemon. This is intended
to provide a few different features:
- Perform log rotation for EdenFS's output and the output of any of its
spawned children processes.
- Help schedule restarts of EdenFS when the system looks idle.
- Provide a single process for the system to manage across graceful EdenFS
restarts, to make management slightly simpler.
This initial commit does not perform graceful restarts yet, but has the basic
daemon management and log rotation present.
