Add specific serializer for SimpleReplicatedLogEntry
JFR shows a lot of re-allocations of the backing byte [] when
serializing SimpleReplicatedLogEntry. We can pretty closely
estimate the total serialized size with some reasonable padding
since the Payload is already serialized. Introduce a
specific akka serializer for this.
