Notes
- Added onResolved instrumentation hook to apply instrumentation prior to module load. - This hook fires after the module filepath has been resolved just prior to the module being loaded by the CommonJS module loader. 
- Fixed issue where recordConsume was not binding consumer if it was a promise 
- Pinned mongo versioned tests up to 4.2.0 until we can address #982 
- Introduced a context management API to be used in place of manually calling tracer.segment get/set.
