Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(m, *args, &block) ⇒ Object

echanges.dila.gouv.fr sometimes returns a local IP (192.168.30.9) for the host in #makepasv. We can store the first host received (which we assume to be good), and return it every time. However, even with a good IP, the next command times out. So, we instead retry the entire command with a new client, after closing the old client.
