Backport of PR #50356

What does this PR do?

This PR handles cdrom disks devices in the virt module. When updating VMs created outside of salt virt module we would hit problems since these devices can have no attached source.

What issues does this PR fix or reference?


Previous Behavior

Run a virt.update on a VM that has a cdrom device with no ISO attached. The salt call will fail with a message saying None is not an iterable type.

New Behavior

Running a virt.update doesn't trigger an exception and keeps the cdrom (or floppy) device intact.

Tests written?

Disks like cdroms have no source element. We need to handle iit in the
disks comparison or we'll have exceptions when updating VMs that haven't
been generated by salt virt module.
Disk devices can be of several types and we need to handle them in order
to update existing VMms with floppy or cdrom devices.
cdrom devices are particularly interesting since they can also have no
Using a dict breaks the disk order which might be of importance to
users. It only hides the disk name from the template rendering, but
that one property wasn't used.
While updating a domain, we need to ensure the disks are in the order
defined by the user.
Ensure the disk target devices are unique within the disks in the new
list before diffing them. Libvirt will reorder the disks based on their
targets. If the users gives a disk order that is not consistent with the
currently running VM, then it's his fault giving us wrong data.
