1. kola/qemuexec: Add a wwn option for scsis disks …

   Add a customizable WWN option for kola DiskSpec to have reliable links
   under `/dev/disk/by-id/`. With this change kola qemuxec can be run like:
   `kola qemuexec -D "5G:channel=scsi,wwn=007"`
   
   Resulting in the following links:
   ```
   [core@localhost ~]$ rpm -qa sg3_utils
   sg3_utils-1.48-1.fc40.x86_64
   [core@localhost ~]$ ls -l /dev/disk/by-id
   total 0
   lrwxrwxrwx. 1 root root  9 Apr  5 09:05 scsi-30000000000000007 -> ../../sda
   lrwxrwxrwx. 1 root root  9 Apr  5 09:05 wwn-0x0000000000000007 -> ../../sda
   ```
   
   This is motivated by recent changes in sg3_utils [1] which
   removed some udev links.
   At least one of our tests [2] relying on this started failing.
   This patch was suggested by @jlebon [3]
