Support Manual Control Mode

[EdHurtig]

See ParadigmHyperloop/hyperloop#47 and ParadigmHyperloop/manual_client#1. We should be deprecating manual_client soon and implementing the functionality over the Web -> ODS -> Pod interface

[EdHurtig]

I envision a panel expands whenever the pod's mode changes to Manual with all the controls. Changing any of the controls will issue a new manual command as documented in ParadigmHyperloop/hyperloop#47 to ODS.

There should also be a new modal created called Change State with a dropdown/list of all the states to change to and a button to execute the state change. This will allow the pod to be taken in and out of manual mode
