[Ovmsdev] Generator / V2G metrics

nice work! So the "first" once again goes to the Leaf :-)

Of course you can extend the V2 message protocol. Maybe introduce a new 
message type for that, as "S" and "D" already are quite loaded.

The grid log already contains the generator metrics and should be 
triggered by a change to the gen state metric as well. That's meant to 
log sessions though, not to transport live data.

Car support shouldn't be a parameter (= user config) though, it should 
be a property of the car adaption. Car capabilities have been on the 
rework todo list for some time.
