Dedicate LVM per K8s engine

This MR !154 (merged) extends the LVM partitioning to the plain flavor. However this partitioning was only design for RKE2 deployment so for Kubeadm the partitioning does not fit well and could cause issues.

This MR fixes the situation by declaring two partitioning models:

• One inherited from the block-device-kanod-lvm called block-device-rke2-kvm used only for RKE2 flavors
• One called block-device-kubedam-lvm which take support the mount points for containerd and etcd with Kubeadm flavor. It is worth mentioning the /var/lib/etcd volume should must be formatted with xfs instead ext4 to avoid lost+found folder preventing preflight/init of kubeadm.

Below the output of OpenSUSE kubeadm partitioning:
