Document the unit for every metric in the Metric enum #279
Description
What's needed?
The Metric enum variants do not have their units documented. This will cause confusions and bugs.
For reference, we stick to using base SI units for these metrics. So,
- voltage: V
- current: A
- DC/AC-active power: W
- AC-reactive power: VAr
- AC-apparent power: VA
- energy: Wh, VArh, VAh
Proposed solution
We need to document every variant here, and specify their units.

Alternatives and workarounds
Until this issue is resolved, the units can be referred to from electrical.proto. While the data structures in this file are very different from those in metric_sample.proto, the units of the metrics are unchanged.
