Summary
Use the RPC as the source of truth for the publisher list & number of active feeds for insights hub.
Rationale
Previously we were using clickhouse to drive this data, however clickhouse can be inaccurate or delayed for a number of reasons.
When I originally built this I misunderstood and thought publishers would only show up in the rpc if they had a data point for the last slot, but in fact publishers show up regardless of if they are actively publishing or not.
So this PR moves to the more accurate source of truth, the chain itself.
How has this been tested?
