This mechanism can sit in resharding_util.h or in the ReshardingCoordinator/StateMachine.

If done before SERVER-49566, temporarily call flushRoutingTableCacheUpdates and do waitForMajority afterwards.

The refresh mechanism for this ticket will send _flushRoutingTableCacheUpdatesWithWriteConcern to a list of shards, but will refresh the list of shards serially and not implement retryable refreshes. 

The additional functionality will be done in SERVER-50424
