             throws Exception
        Cancel a query as identified by the queryId. This method is non-blocking so the query may still run for a while after calling this method. This cancel method can be called multiple times.
        Parameters:
        queryId - the unique Id assigned to the query by the broker
        timeoutMs - timeout to wait for servers to respond the cancel requests
        executor - to send cancel requests to servers in parallel
        connMgr - to provide the http connections
        serverResponses - to collect cancel responses from all servers if a map is provided
        Returns:
        true if there is a running query for the given queryId.
        Throws:
        Exception
