 It would be handy if the following roles were split up:

   1) The list of IP:Orport:Identity to which every relay should upload
 every descriptor.
   2) The list of IP:Orport:Identity from which caches should expect to
 find canonical consensuses and descriptors.
   3) The list of IP:Orport:Identity from which non-caches should expect to
 bootstrap consensuses and descriptors. (See 'fallbackdir')
   4) The list of keys that must sign a vote or a consensus.
   5) The list of IP:Orport:Identity that authorities use when sending and
 receiving votes.

 Splitting roles up in this way would better prepare us for an
 implementation of prop#257 down the road.
