Merge Functionality From Prior Compatibility Benchmark Suite

[jonahharris]

Hey, Todd!

This is awesome. is this designed to eventually be merged with, or replace, the prior compatibility testing suite? That one had a good breakdown of the tests by category along with specific test/pass/fail counts.

It's possible but the other test was written to evaluate cloud services like DocumentDB and Atlas. These necessitate a larger test array for sharding, vector search, replication, etc. None of which are required for this new class of nosql proxies. All of the actual javascript tests are included in mongo source here: https://github.com/mongodb/mongo/tree/master/jstests
