The following passthrough test suites will be added:

• replica_set_reconfig_jscore_passthrough
• replica_set_reconfig_stepdown_jscore_passthrough
• replica_set_reconfig_kill_nodes_jscore_passthrough

We will start a 5-node replset with 3 nodes having vote: 1. The test suites periodically and randomly remove or add a node by changing the node’s vote so that the config has 1-5 voting nodes. replica_set_reconfig_kill_nodes_jscore_passthrough kills or restarts a node randomly to cover unclean shutdown and durability issues. The shutdown hook and reconfig hook will make sure a majority of nodes are alive at any time.

These suites should be run with readConcern: majority, writeConcern: majority, causal consistency, readPreference: primary, and retryable writes so that reconfig does affect the operations.
