Make installer able to handle /dev/disk/by-id/ devices

[ableischwitz]

This change introduces the detection of DRIVEn /dev/disk/by-id/xxxx devices. Additionally to the different nvme naming for partitions, those disks get a -partx added to the device - instead of a single number

Currently the installer simply adds a "1", "2",... to the device - which is fine for /dev/sda, /dev/sdb,* - there is already a exception for nvme devices, which also needs to be implemented for /dev/disk/by-id/* devices. Not having this ability to provide static device names renders the installer to become unpredictable with 3 drives if only two of them should be configured. This change also allows devices to be listed with their wwm-0x5xxxx name as they also reside in /dev/disk/by-id.
