Test Rollback from upgrading to downgrading similar to https://github.com/mongodb/mongo/blob/master/jstests/replsets/rollback_set_fcv.js

Test that we can perform rollback between a rollback node in downgrading syncing from a node in latest and vice versa, and between a rollback node in downgrading sync from a node in last-lts and vice versa (similar to https://github.com/mongodb/mongo/blob/master/jstests/multiVersion/genericSetFCVUsage/rollback_downgraded_to_latest.js)
