glusterd: Introduce option to limit no. of muxed bricks per process
This commit introduces a new global option that can be set to limit the number of multiplexed bricks in one process. Usage: `# gluster volume set all cluster.max-bricks-per-process <value>` If this option is not set then multiplexing will happen for now with no limitations set; i.e. a brick process will have as many bricks multiplexed to it as possible. In other words the current multiplexing behaviour won't change if this option isn't set to any value. This commit also introduces a brick process instance that contains information about brick processes, like the number of bricks handled by the process (which is 1 in non-multiplexing cases), list of bricks, and port number which also serves as an unique identifier for each brick process instance. The brick process list is maintained in 'glusterd_conf_t'.
