1. Stop fold when a vnode reaches page size …

   Currently, 2i pagination may, with a sufficiently slow participating
   node, receive many, many more keys than the page size (max_results) from
   all the other participating nodes.
   This change will track how many results have been received per vnode,
   and send a stop fold message to a vnode as soon as it has sent more than
   max_results.
   Note, however, that vnodes will send in chunks possibly much larger than
   the page size (100 items at a time I believe). It would be ideal to pass
   max_results to the folding function and have it stop when it reaches
   that number. But that will have to wait until later. Release is near.
   This should at least prevent a worst case of unbounded growth that could
   consume all the node memory
