Why are these changes needed?
The num of active batches can go up and down, so it has to be a Gauge.
However, Gauge isn't really a good fit for tracking active batches, because it will get set to 0 at Node start, which is wrong for accounting.
Here we track two things:
Both of them are counters (avoid using Gauge)
On the dashboard, the diff between the two is the num of active batches.
