Why not just have each node use local config file's value instead of messing w/ header?

Some how i expected this question :), the idea was to save some bytes by using header. (Now
i am thinking it is micro optimization :))

v2 attached doesn't mess with header

> Deploying 1.2 against a cluster whose clocks are not synchronized will cause *every*
request to timeout.  Suggest adding a {{cross_node_timeout}} option defaulting to false that
users must explicitly enable after installing ntpd.  Otherwise we fall back to the pessimistic
case of assuming the request was forwarded to the replica instantly by the coordinator.
