Description
Historically FeeRateGovernor is created and advanced from parent for every new bank. Its original intention is to adjust lamports_per_signature based on cluster throughput, which is no longer the case, lamports_per_signature has been statically 5,000 since 1.8 (or even earlier). However FeeRateGovernor still has an active side effect: its lamports_per_signature is used by hundreds of tests to set zero fee for test transactions. Tho same can be achieved without having to store bank.fee_rate_governor.lamports_per_signature to blockhash_queue. Doing this pave the way to eventually sunset FeeRateGovernor from bank, and its snapshots.
However change what's stored into RecentBlockHashs account changes account-delta-hash, which is part of BankHash (until LTdLt9Ycbyoipz5fLysCi1NnDnASsZfmJLJXts5ZxZz). Therefore this change requires feature gate (or wait till LTdLt9Ycbyoipz5fLysCi1NnDnASsZfmJLJXts5ZxZz is activated everywhere).
