Description
Make FCV dowgrade fail to a version that doesn't support user write blocking under any of the following scenarios:
(a) User writes are currently blocked
(b) A SetUserWriteBlockModeCoordinator is running (applies to the configsvr exclusively)
For replicaSets (which don't use SetUserWriteBlockModeCoordinator ), proper synchronization must be ensured between check (a) and the setUserWriteBlock command.
