 """Apply remote `method` asynchronously or synchronously depending on the value of `nowait`. :param method: The name of the remote method to perform. :param args: Dictionary of arguments for the method. :keyword nowait: If false the call will block until the result is available and return it (default), if true the call will be non-blocking and no result will be returned. :keyword retry: If set to true then message sending will be retried in the event of connection failures. Default is decided by the :attr:`retry` attributed. :keyword retry_policy: Override retry policies. See :attr:`retry_policy`. This must be a dictionary, and keys will be merged with the default retry policy. :keyword timeout: Timeout to wait for replies in seconds as a float (**only relevant in blocking mode**). :keyword limit: Limit number of replies to wait for (**only relevant in blocking mode**). :keyword callback: If provided, this callback will be called for every reply received (**only relevant in blocking mode**). :keyword \*\*props: Additional message properties.
