    glfs-mgmt: fix connecting to multiple volfile transports

    Problem:
    [
            {"host":"1.2.3.4", "port":"24007", "transport":"tcp"},
            {"host":"/var/run/glusterd.socket", "transport":"unix"}
    ]

    Consider the above case where we have two volfile servers, each
    has different transport type, we first try to connect to server1
    which has transport type "tcp" let's say we found that host address
    is invalid, now we pick the next available server2, in our case
    it is of type "unix" and try to connect to it.

    but we fail to connect to it even we have right unix path, because
    multiple volfile servers with different transport type is not taken
    care currently.

    Solution:
    Every time we receive a  RPC_CLNT_DISCONNECT event in mgmt_rpc_notify,
    we need to check the transport type of the volfile server in the list
    and set the keys "transport.socket.connect-path" or "remote-host"
    accordingly.
