[Ovmsdev] Advice - mapping I3 data to the standard metrics

You propose "v.e." probably due to the "v.e.charging12v" and ".aux12v" 
flags? I think these are misplaced in "v.e." (as some others). We should 
probably rename them mid to long term.

"e" has been used (also by me) as a pool for stuff that didn't fit 
elsewhere, but we probably should try to clean this up so its 
"environment" again (meaning any kind of environmental influence or 
control). The DC converter doesn't really fit there.

I would rather place the DC converter metrics in the charger namespace, 
e.g. "v.c.12v.temp", as the DC converter often is a part / subsystem of 
the charger, and it's main purpose normally is charging and assisting 
the 12V battery.

Another option could be the 12V battery namespace, e.g. 
"v.b.12v.c.temp", but the DC converter isn't a subordinate of the battery.

In all cases I'd like to keep the "12v" tag associated here, so all 12v 
related metrics can be queried by a simple "me li 12v" and subscribed to 
with a single topic pattern.
