Add in MachineState to the Control trait, HTTP Endpoint

[paultag]

This is a first step as we start to chip away on #68 slash #49 and others.

This will add a standard part of our "Control" trait to check on the state of a printer -- is the printer running? idle? paused mid-print? Broken?

I implemented this for Moonraker (since I was able to test it), and stubbed in Unknown elsewhere. USB is doable here -- and I think we can do Bambu, but that may wait until I get into the office to play with it myself.

yeah i would be really nice to have the status of the printer in the modeling app

[jessfraz]

also i just made a mental note to myself for the hackathon im gunna have to move the printers to the guest network or allow them on the guest network as well as machine api

[jessfraz]

will figure out something because i do like the guest network being isolated from the rest of the office
