feat: adding instrumentation support for mongo-driver/v2

[AlaricWhitney]

Adding the mongo-driver/v2 instrumentation.

This is a copy/paste of the v1 instrumentation, and was modified to adhere to the mongo-driver/v2 requirements.

Notable differences:

• mtest was removed in v2. Replaced with drivertest in the unit testing.

This addresses PR #6419
