Battery Properties #33

No matter how https://github.com/mozilla-iot/gateway/issues/1439 goes I think it'd make sense to have schema types for both a percentage based battery property and a boolean property for low battery.

Even if you only have voltages, you should still be able to give a percentage, since you should know your device's minimum required voltage and maximum battery voltage. And if either of those parameters is missing there's still the VoltageProperty for raw values.

Agreed, these would be great additions.

Battery info can be quite complex. It should almost be a thing on its own.

Factory specification (watt-hours or ampere-hours)
Maximum capacity (watt-hours or ampere-hours)
Remaining capacity (watt-hours or ampere-hours or percentage)
Warning/critical thresholds: (watt-hours or ampere-hours or percentage)
Charging/ Discharging (boolean, enum or rate of discharge as a float)
Remaining time until full / empty (duration)
Time since last full / empty (duration)
Defect detected: (boolean or event)

Number of cells and balancing if we want to go deeper, I am not on expert on BMS but I know it's not something simple.
