the class GetPeersHandler method handle.

 * @param restRequest the {@link RestRequest} that contains the request parameters.
 * @param restResponseChannel the {@link RestResponseChannel} where headers should be set.
 * @param callback the {@link Callback} to invoke when the response {@link ReadableStreamChannel} is ready (or if
 *                 there is an exception).
