## Summary
* Changed the office LAN convenience function to a class with a registry. Now, plugin can register custom node adders.
* Added ability to define `node_sets` in the config that map to `NetworkNodeAdder` subclasses
* Made airspacefrequency into a DTO class again to make management simpler.
* Moved the node registry out of `HostNode` and `NetworkNode` into `Node`
* Changed game.py to check the hardcoded node types before the node registry (this will change once I add ConfigSchema to all node subclasses)
* Made `show` method of the network container show all nodes, including ones registered at runtime.
## Test process
* Existing tests passed.
* Added unit tests for node adders

## Summary
This PR introduces the `last_response` attribute within Terminal, similar to that seen within the C2 suite. The aim of this is to resolve the bug seen when using Terminal, in that when sending remote commands to execute, the RequestResponse does not indicate whether the command was successfully actioned, just that it was sent.
## Test process
New test to check that `last_response` contains the correct ReqestResponse following remote command execution
