- Added .show() methods to new router classes to enable inspection of the components as you would a real router.
- Removed gateway from the NIC and added default_gateway to Node so that Node has a single default gateway.
- Added some routing tests to check that ping can be performed when router between subnets.
## Summary
- Add an object that holds the entire simulation, and a container for the network that keeps track of a list of nodes and links.
- Implement `describe_state()` for all existing sim components and take advantage of the inheritance relationships to avoid repetition.
- Fix some minor mistakes like typehints and indentation errors.
- Write a jupyter notebook which uses the python API to create a simulation and verify that it's `describe_state()` method outputs a correct value.
- Currently the notebook creates the simulation in a janky way, because the API for simulation creation is not fleshed out yet. Further tickets have been added to the backlog to address some of these shortcomings. They are:
- #1790
## Test process
I have tested that the notebook runs and that after populating a simulation, the describe_state function returns a dictionary full of only serialisable data types.

This ticket also makes a small amount of progress against: #1705, it adds a shell of a network class, but only by creating the class, not implementing any functionality.

#1714: fixing minor error in test + adding a check for existing uuid when adding file

## Summary
- Network Hardware - Added base hardware module with NIC, SwitchPort, Node, Switch, and Link. Nodes and Switches have
fundamental services like ARP, ICMP, and PCAP running them by default.
- Network Transmission - Modelled OSI Model layers 1 through to 5 with various classes for creating network frames and
transmitting them from a Service/Application, down through the layers, over the wire, and back up through the layers to
a Service/Application another machine.
- system - Added the core structure of Application, Services, and Components. Also added a SoftwareManager and
SessionManager.
- #1706 - Got the core Node class build and working with ARP and the ability to ping another node. Added some basic tests in. Next job is to create the Node subclasses. Then move ARP and ICMP into a ser
- #1706 - Added some extra logging
- #1706 - Started adding the core node software required by all nodes. Made some tweaks to the Frame to have send and receive timestamp.
- #1706 - Got the code services, application, and process base classes stubbed out. Need them now so that I can leverage them for core node services required.
- #1706 - Tidied up the SysLog ARPCache, and ICMP classes and integrated them into the Node. Tidied up the base implementation of SoftwareManager and SessionManager. Tidies up the public API for Service
## Test process
Tests really asses how components fit together and that it all does work. They tests don't yet check that things like ICMP work, as in the ping is received and responded to.

## Summary
This PR implements an outline of accounts and domain controller. However, the main contribution is the permissions system and the changes to `SimComponent`. The domain skeleton will probably change after the node/folder/file/app/service classes exist.
The big idea of the permissions is that the simulator itself is built in a way that permits everything, i.e. the methods of each component that make something happen don't have any permissions checking. Therefore, if you can use primaite without any agents and you will essentially have superadmin, any action you perform will go through. The permissions come into play when you try to interact with the components via the actions. Every action has a configurable permission validator attached to it that will either allow or block the action.
For this reason, I've had to modify the way actions work. To keep everything neatly contained, there is a new Action class that holds a reference to both the action function itself but also to a permission validation function.
## Test process
Unit tests and integration tests.
I will write the design documentation for permissions and update the design for SimComponent once others are happy that the design makes sense.
