Option to disable banlist metrics

[mmilata]

I'm using a banlist that's got ~5000 entries which make the exporter output huge. It's not fatal but it's not ideal either. I wonder if there's some more elegant solution than introducing "boolean" env variable to turn it off?

Instead of the bitcoin_ban_created and bitcoin_banned_until metrics, I expect you probably only care about aggregate ban metrics, not any of the per-peer metrics.

Maybe just a high level bitcoin_banned_peers gauge, along with the ability to turn off the per-client metrics.

Yep, exactly.
