    [docker] clarify on {MASTER,TSERVER}_ARGS
    
    This patch clarifies on how DEFAULT_ARGS are combined with
    MASTER_ARGS and TSERVER_ARGS to build an effective set of
    arguments to run kudu-master and kudu-tserver correspondingly.
    
    This patch doesn't contain any functional changes.
