 Description   

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.

Note: This was partially captured in DOCSP-7544. For example, see [this commit](https://github.com/mongodb/docs/commit/4ed15e0b01232b24de9878604a936cdae34a0a16#diff-5647b554183a3604f97c3ca7ca311f2fR198-R211)

However, we still need to document in the Downgrade section that the default RWConcern settings are lost, but mongos routers may continue applying those defaults for up to 30 seconds after downgrading fcv.
