Acceptance Criteria

If the driver exposes the authentication mechanism in a public API, then:

• Deprecate MONGODB-CR and raise an error indicating to the user that MONGODB-CR is no longer supported in MongoDB 4.0 and subsequently the current driver version.

If the driver does not expose the authentication mechanism in a public API then:

• Completely remove MONGODB-CR functionality from the driver.

If not already done with DRIVERS-2938 sync the auth legacy spec tests to https://github.com/mongodb/specifications/pull/1611
