Added queue properties to bindQueueConsumer and bindPrivateQueueConsumer

Problem

Version 0.2.1 cannot bind to persistent/durable queues.

The implementation of bindQueueConsumer (in the _ExchangeImpl class) invokes channel.queue only with the queueName, so the durable parameter always defaults to false.

https://github.com/achilleasa/dart_amqp/blob/0231485e4584487eb7faefe2ecb1a6f3396338d4/lib/src/client/impl/exchange_impl.dart#L88

If the queue did not exist, it was created as non-durable.

If it did exist, an exception would be thrown because the existing queue has durable=true and this line is trying to get a queue with durable=false.

Solution

This pull request adds durable (and all the other parameters the queue method can have) to the parameters of the bindQueueConsumer method. That way, the invoker can indicate they want to bind to a durable queue. For example,

exchange.bindQueueConsumer('my_queue_name', noAck: false, durable: true);

For consistency, it does the same thing to bindPrivateQueueConsumer.

The change is backward compatible, since the added parameters are all named parameters that are either nullable or have default values.

Thanks. I think I've done it correctly, but am not sure if I have used the correct sequence of git commands.
