[PATCH] isar-installer: add mdadm support and filter out RAID member disks

[Kasturi Shekar]

The installer now conditionally includes the `mdadm` package,
based on the presence of the `raid` feature in `MACHINE_FEATURES`
Additionally, the device selection dialog is updated to exclude
physical disks that are members of a RAID volume.
