/**
 * The REST resource for the Coordinator. This describes the RPCs which the coordinator
 * can accept.
 *
 * RPCs should be idempotent.  This is important because if the server's response is
 * lost, the client will simply retransmit the same request. The server's response must
 * be the same the second time around.
 *
 * We return the empty JSON object {} rather than void for RPCs that have no results.
 * This ensures that if we want to add more return results later, we can do so in a
 * compatible way.
