Description
Downstream Change Summary
setDefaultRWConcern can only be run when a cluster is in the fully upgraded to FCV 4.4 state.
Downgrading FCV from 4.4 to 4.2 will cause any cluster wide read write concern defaults to be lost, but mongos servers may continue applying the defaults for up to 30 seconds.
