Problem
The presence of the PeriodicShardedIndexConsistencyChecker thread causes unintended refreshes on shards in all config server stepdown suites. Js tests that rely on a shard's metadata being stale can sporadically fail due to this thread running on stepup.
Possible Solutions
- Auditing all jstests that rely on stale shard metadata and disabling the periodic thread (this has been done before).
- Disabling the thread altogether on config server stepdown suites, and enabling it on targeted tests that test the behavior of the periodic thread.
