Introduce optional parameters for 'rabbitmqctl list_queues', to filter down/up queues.

[Ayanda-D]

Initially proposed as part of #357.

Adding optional parameters for list_queues to display up or down queues only would also be useful. Possible usage would maybe be as follows;
list_queues [--up] [--down] [-p <vhostpath>] [<queueinfoitem> ...]

I'm going to implement it for master in #683
Is the stable version needed at all or it could just wait for the PR above?

@binarin we wouldn't mind shipping it in 3.6.x.

[binarin]

rabbit_cli.hrl contains --offline and --online options, may I use them instead of --down and --up?

[michaelklishin]

@binarin that sounds reasonable. I wouldn't mind using --available and --unavailable over --up and --down if we were after the most descriptive names.

I personally think that --online and --offline are good enough.
