use config version to trigger replication configuration instead of state Replicated

Summary

• fix: master is now promoted when configuring the replication

• chore: don't send lsn in response to proc_replication

Nobody cares about the lsn

• fix: don't promote any replicas when configuring replication in the middle of master switchover

• fix: Replicated is no longer a possible state

• feat: use config version to trigger replication configuration

• fix: used to computed parenthesis depth incorrectly in pico.raft_log

• fix: used to panic in pico.raft_log sometimes

• feat: also bump target vshard config version in update instance

• refactor: allow multiple additional dmls when updating instance from governor

• feat: bump replicaset target_config_version in update instance

• refactor: add [current|target]_config_version columns to _pico_replicaset

Not used yet

• feat: proc_update_instance now uses Dml::Update instead of Dml::Replace

It's called proc_update_instance, not proc_replace_instance, duh!

• refactor: don't use String as error type

• chore: cleanup code formatting
