Consider introducing a command that deletes all queues in a vhost

[michaelklishin]

Can potentially be very dangerous but also occasionally useful. Suggested by @Gsantomaggio.

This is the way:

for vh in $(rabbitmqctl list_vhosts -s); do  for q in $(rabbitmqctl list_queues name -s --vhost $vh) ; do rabbitmqctl delete_queue --vhost  $vh $q; done done

I added other rabbitmqctl commands here

it is open for a while, can we close it? @michaelklishin
