No longer use the ssh keys in the Emulab database when the protogeni
user is a local user. Instead, all users have to send along their keys in the RedeemTicket() call, and those keys land in the new Emulab table called nonlocal_user_pubkeys, and tmcd will use that table when sending keys over local nodes. This change removes the inconsistency in key handling between slivers created locally and slivers created at a foreign CM.
