added list_queues commands

rabbitmqctl has these list commands (list_queues, list_exchanges, list_bindings etc), which accepts vhost argument  with -p parameter (which is not mandatory, if not provided, command is executed on vhost '/' ).

Also these commands accept various number of arguments which defines the output of these commands.

But since we cannot provide -p on salt command line, I have split it in two separate salt commands. 

If this is ok, I can implement other commands in the similar format.
