## 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
Implements the Command and Control applications to the quality and capability needed for the TAP001 expansion and lays the foundations for all the features required for TAP002 (Next Release).
The C2C suite contains three new applications:
**1. Abstract C2**
Base class for the C2 Server and the C2 Beacon. Controls the main internal logic of both applications but with a couple of abstract methods which each class defines differently.
**2. C2 Server**
The C2 Server takes red agent actions and converts the action options into C2 Commands which are then passed to the C2 Beacon.
The output of these commands is sent back to the C2 Server and then returned back to the red agent.
**3. C2 Beacon**
The C2 beacon uses the Terminal and the Ransomware Applications to perform different commands which it receives these commands and executes them and returns the output.
The C2 beacon can also be configured by the Red Agent to configure the current networking behaviour.
For a much more detailed description please refer to the .rst documentation and the notebook which demonstrate and describe the functionality very explicitly.
Lastly the wiki page also provides more information around the design work for this feature.
[Command and Control](/Welcome-to-PrimAITE!/Design/[~In-Progress~]/Command-and-Control)
Worth noting that some changes were needed that were unseen during the design page but the overall goals of the feature have been accomplished.
## Test process
Tested via notebooks and a series of e2e tests.
