prove out op-conductor in localnet

set up 3 sequencers, each controlled by op-conductors p2p'd via raft consensus

update localnet tests CI to kill 1 op-node, another should take over sequencing

decrease the initial btc blocks because 3000 is excessive (this will need testing over time)

updated l2 block time to 2 seconds, instead of 1, it's easier to follow this way IMO
