Summary of Changes

This PR does two things:

• Adds a testing variant that runs with TLS enabled in CI
• Addresses the concerns with the backpressure test fromNODE-7394 (you can confirm that this test is running and passing in 8.0+ CI variants in the TLS tests task)

Along the way, I encountered a few issues:

• Auto connect doesn't work properly when TLS is enabled: https://jira.mongodb.org/browse/NODE-7398
• Some test suites are failing with TLS enabled: https://jira.mongodb.org/browse/NODE-7408

So, some test suites are skipped for now. Other suites have explicit calls to MongoClient.connect() to avoid NODE-7398.
