Right now we call our validate.py hook after each JS test, but not after the suite/during shutdown. Since we turned off full validation in SERVER-110331 for validate calls on active nodes, we should make sure that full validation is still run during/right before shutdown. If this is not covered by invocations of validate_collections_on_shutdown.py, we should create a new python hook and run it after each resmoke suite concludes. 

It's not possible to know if the node is in shutdown/the oplog applier is not active in the existing python hook, so we can't modify the options there to account for this case, which is why we would need to create a new hook.
