If this looks easy (PoC on say Compass repo that tests can pass on Travis), just estimate and complete it as part of this ticket. If it looks hard (i.e. not fix-able in a sprint), turn this into an epic and track each upgrade individually as a task.

Ideally complete this task for all compass repos in 10gen and all supported (see COMPASS-906) mongodb-js repos.
