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.
