Feature Request

Summary

Related to #2927. We should make the consensus reactor, upon seeing a vote message, check if the vote is late and ignore it, outside of consensus state's processing.

This will Save WAL writes, and time under consensus mutex

Problem Definition

On Osmosis RPC nodes, we see 2 million late votes per hour, which I think should mean considerably more work load under the consensus mutex.

Proposal

Add logic right here (https://github.com/cometbft/cometbft/blob/main/internal/consensus/reactor.go#L360-L361 ) of the form:

if vote.Height < height {
// add to late vote metrics
  return
}
