  1. Setup the new "limit" qualifier for bind-to

    Add a new qualifier for the "bind-to" directive:
    
    "LIMIT=n" limits the number of processes bound to each eligible
      representative of the specified type to the given number. For
      example, speifying "--bind-to l3:limit=2" would direct PRRTE
      to bind ranks to the L3caches, limiting the number of processes
      bound to each l3cache to two - i.e., bind 2 processes to a
      given l3cache, and then move on to the next.
    
    Add new help text to "prun" and "prterun" to include new "limit=n"
    modifier for the "bind-to" directive.
    
    The binding algorithm has not been updated to support this yet.
    Requires some additional work that will be done in a later
    commit.
