Description

As part of the Lustre release testing, we run upgrade and downgrade of Lustre from/to the last LTS version and, if different from LTS, the last release. We run this for ldiskfs and for ZFS and we for rolling, one server type then clients at a time, and clean, all at once, upgrade/downgrade.

Let's automate this process.
