onboard dmtest-python
this depends on kernel-tests#1667 (closed)
I imagine will change the https://gitlab.com/redhat/centos-stream/tests/kernel/kpet-db/-/blob/main/cases/storage/lvm/device-mapper/index.yaml
It will provision a beaker bare metal machine with additional partitions like https://gitlab.com/redhat/centos-stream/tests/kernel/kpet-db/-/blob/main/cases/storage/lvm/device-mapper/partitions.xml.j2
We can change any of this if needed.
