Support CQL queries when getting list of validation rules

@Override
  public void getTenantRules(int offset, int limit, String query, Map<String, String> okapiHeaders,
                             Handler<AsyncResult<Response>> asyncResultHandler, Context vertxContext) {
    try {
      validatorRegistryService.getAllTenantRules(tenantId, limit, offset, query, reply -> {
        if (reply.succeeded()) {
          RuleCollection rules = reply.result().mapTo(RuleCollection.class);
          asyncResultHandler.handle(
            Future.succeededFuture(GetTenantRulesResponse.respond200WithApplicationJson(rules)));
        } else {
          String message = "Failed to get all tenant rules";
          logger.error(message, reply.cause());
          asyncResultHandler.handle(
            Future.succeededFuture(GetTenantRulesResponse.respond500WithTextPlain(message)));
        }
      });
