This patch implements the `serverroles` API plugin which introduces the
following commands:
* server-role-show SERVER ROLE: show status of a single role on a server
* server-role-find [--server SERVER [--role SERVROLE [--status=STATUS]]]:
find role(s) SERVROLE and return their status on IPA
masters. If --server option is given, the query is limited to this
server. --status options filters the output by status [enabled vs.
configurer vs. absent]
