simulator: Add support for networking (v1)

This change adds support for networking in the simulator. 
As outlined in #84, the network model doesn't model individual packets, 
but instead considers dynamic flows between network devices. 
This pull request adds the bare-minimum implementation necessary to model network traffic. 
In the future, we will add advanced functionality such as routing and other L3 concepts. 

* Add core model for network simulation
* Add model for network adapter that attaches to machine
* Add virtual network switch to bridge traffic between hosts.
