// Start is a blocking function that monitors Consul for replication controllers.
// The Farm will attempt to claim replication controllers as they appear and,
// if successful, will start goroutines for those replication controllers to do
// their job. Closing the quit channel will cause this function to return,
// releasing all locks it holds.
//
// Start is not safe for concurrent execution. Do not execute multiple
// concurrent instances of Start.
