In the series we add reporting replication.X.downstream.lag value
to complement replication.X.upstream.lag.
Note that this value represent exact counter part of upstream.lag
since detailed statistics about qsync and synchronous acks has
a different meaning and gonna be implemented in #5191.
Please take a look once time permit. As far as I can tell we
can safely start encoding timestamp into vclock message without
affecting any old instances. I've grepped the 1.10.x series
for potential problems and didn't find any sign of.
