fix: replication stream broke due to parser changes

[levkk]

• fix: the replication stream was broken due to parser changes - required us to pre-parse the statement
• fix: don't acknowledge end of WAL until we see data - may cause synchronization issues when reconnecting
• feat: add resharding_only flag on databases to be used for resharding and not serving queries
• feat: track replication lag while replicating, log once a second
