Provide a way to specify Consumer Arguments in Receiver.consume* methods

[maciejharczuk]

It looks like it's not possible to specify Consumer arguments when using any of the Receiver's consume* methods. I'm not sure if there was any use for them in the past, but with RabbitMQ 3.9 streams, if consuming them with AMQP client, the x-stream-offset argument is used to specify the offset at which consumption will start.

Since we already have the ability to pass ConsumeOptions to Receiver.consume* methods, I suggest we add an empty-by-default (or null) map of args to that class, so that later we can pass it to channel.basicConsume.

@acogoluegnes, is there a plan to release this any time soon?

[acogoluegnes]

It's in 1.5.4 and 1.4.8.RELEASE.

OK, I must have missed it because of the not updated releases page. Thanks.
