Description

Currently, the MonClient (See src/mon/MonClient.h|cc) hunts for a mon to connect to by iteratively choosing a random one and attempting to connect until a successful connection is established. In cases where one or more mons are down, this can take a significant amount of time increasing load on the cluster. This feature involves reworking MonClient to allow it to hunt for several mons in parallel and connect with the fastest one to respond.
