 Description   

In addition to the testing in SERVER-41183 for homogeneous clusters, we should add a multiversion test to provide coverage for our upgrade/downgrade path. Specifically, we want to test that a Change Stream running on a 4.3/4.4 mongod can correctly operate on an oplog for a 4.2 or FCV4.2 mongod.

We want to backport this to 4.2 in order to have test coverage for the 4.0->4.2 upgrade path.
