get a count on how many beacons we process.

[kaisbaccour]

Ugly solution : by following sink ash (probably not accurate).
Better solution : following the gateway and extract foreach customer. Then on grafana we can aggregate the data and figure out how much we have total.

[webmaster128]

With the 0.12 gateway, the client can loop over the Customers { ... } query and get

1. The number of customers
2. The sum of requested_beacons

Both data can be prepared in TypeScript and we only export two gauge values to prometheus

[kaisbaccour]

This is the kind of metric that could be nice to have.
We don't need the sum aggregation in the metrics because we better aggregate that at the visualisation level
