Per SERVER-21949, there is a new validation testing hook that we should be running. The following suites should include this new hook:

• core
• concurrency
• concurrency_replication
• concurrency_sharded
• jstestfuzz
• jstestfuzz_replication
• jstestfuzz_sharded
• sharding_jscore_passthrough

Note - We can only run the validation testing hook on suites that use a MongoDFixture, ReplicaSetFixture or ShardedClusterFixture. If the suite launches it's own mongod/mongos then the hook cannot be invoked.
