[Feature Request]: Adding external I2C Current/voltage Sensor to Metrics log

Description

As of now The Power metrics log internal Battery voltage, air utilization etc. like we can see here:

As The node I am showing here is a solar node using an external Solar management board and battery pack, the Node itself only sees the 5.1 volt from the external power source over USB.
So I got myself a Ina219 I2C Power monitoring Sensor that also shines up nicely on the overview of the node:

The issue I have is that I dont really see the ups and downs I would normally see in the log when the directly connected battery gets charged and discharged over time.
Would it be possible to implement the I2C measured power readings into the Metrics?

Power metrics graph for all 3 channels of an ina3221 are on the list in the Android graphs discussion. I think* that's what's being worked on next.
