Reconfiguration openSUSE Tumbleweed disk layout && setting up "/var FS" LVM size

 Snapshots below demonstrate abilities of openSUSE Tumbleweed installer to create separated from root BTRFS volume two LVMs for /var and /home (FSs) formatted as XFS  file systems. Next step is deploying F39 WKS Guest with size of virtual disk greater then size of root BTRFS volume, just as POC (Proof of concept) of openSUSE installer flexibility
