...               This test isolates the current leader of the "car" shard and then executes CRD
...               operations on the new leader and a new follower. The isolated member is brought back.
...               This suite uses 3 different car sets, same size but different starting ID.
...
...               Other models and shards (people, car-people) are not accessed by this suite.
...
...               All data is deleted at the end of the suite.
...               This suite expects car module to have a separate Shard.
