#get_node_name(_name, _prefix) ⇒ Object

overriding this from Chef::Knife::Cloud::ServerCreateCommand.

This gets called in validate_params! in that class before our #before_bootstrap is called, in which it randomly generates a node name, which means we never default to the instance name in our #before_bootstrap method. Instead, we'll just nil this and allow our class here to do The Right Thing.
