Allow setting a minimum gas used value to determine whether or not to use a block supplied by the builder API

In a similar spirit to https://github.com/flashbots/mev-boost/issues/273

I think users should be able to express an opinion about the fullness of a block. Currently, block builders will often leave transactions out of a block when volatility is high. The reasons for this are not fully known, however what is know is that blocks have a lower gas used than would otherwise be the case.

One of the purported benefits of delegating block building is that the block builder should be able to fill the block with more transactions than a solo validator.

This would allow solo validators to express their opinions.

L’issue inizialmente non indica alcun file, test o punto di ingresso. Prima mappa come vengono valutati i blocchi della builder API e dove viene gestita la configurazione del validator, poi definisci l’impostazione del gas minimo e il relativo comportamento di accettazione prima di implementare i test e la modifica.

Scritto dal modello di indicizzazione a partire dal testo della issue.
