Add battery precondition signals #703

Electrical vehicles may have a system that prepares the traction battery for driving or charging by making sure that the battery has an optimal temperature for driving or charging. This PR proposes a set of signals for this purpose. The idea is that the signals should be quite generic and fit various type of implementations of a battery precondition system.

Looks like a good start.

Regarding times, shall we require they be in UTC and ISO 8601 format?

I haven't worked through use cases, but the definitions should take into account what happens when "plans change". That is, the battery was being conditioned for a specific time and the vehicle is no longer parked or plugged in, etc. Indeed, the logic will be implemented in the vehicle, but we may need to have signals that represent the state or cause for interruption of the conditioning.
