This is the implementation for Channel.prepare_queue_arguments

Arguments:
arguments (Mapping):
User-supplied arguments (``Queue.queue_arguments``).
Keyword Arguments:
expires (float): Queue expiry time in seconds.
This will be converted to ``x-expires`` in int milliseconds.
message_ttl (float): Message TTL in seconds.
This will be converted to ``x-message-ttl`` in int milliseconds.
max_length (int): Max queue length (in number of messages).
This will be converted to ``x-max-length`` int.
max_length_bytes (int): Max queue size in bytes.
This will be converted to ``x-max-length-bytes`` int.
max_priority (int): Max priority steps for queue.
This will be converted to ``x-max-priority`` int.
Returns:
Dict: RabbitMQ compatible queue arguments.
