rpc.py: add 'discovery' nqn shortcut for nvmf listener RPCs

Browse Source 
Now that users need to explicitly add a listener for the discovery
subsystem, make that a bit easier when using rpc.py.  Instead of
having to type out nqn.2014-08.org.nvmexpress.discovery, allow
user to just specify 'discovery' as the NQN and rpc.py will
convert it to the discovery NQN before sending the RPC.
