Support disk type identifying

[leanenkaa]

Identify and group disk not only by device pattern but also by type of the disk(ssd,hdd,nvme).
So we can use disks with similar type in one LVM volume group.
We can't use device pattern in every case, /dev/sda can be hdd and /dev/sdb can be ssd.

devicespattern can be comma seperated list, so you can use e.g. "/dev/sda,/dev/sdc"
