fetch beacon entries from gossipsub

[LesnyRumcajs]

Summary

See spike at #7364

Right now, when we need beacon entries, we query the https relay; we could avoid our reliance on that by using the dedicated gossipsub topic and feeding it into a cache.

We might also that would somehow resubscribe to the topic in case we don't get queries for longer period.

Completion Criteria

• Feed beacon entries from gossipsub to the drand cache.
• Test that it works correctly, e.g., drop drand https relays and ensure recent queries to MinerGetBaseInfo work fine without it.
• Watchdog

@LesnyRumcajs Hi I would like to take on this issue. And is there is a dedicated communication platform you use, like discord, or slack which I can join to keep sharing updates or ask queries ?

@yashksaini-coder Thanks for your interest, I'd rather this to be done internally. For future, you can check out docs for channels we're hanging around.
