Add support for UUID disk and serial number

[sblanchet]

Add support for TrueNAS Scale

It means that we can also specify the enclosure slot with

• disk serial number
• partition UUID

Implementation details:

• for disk serial number I use the output of lsblk --nodeps -o name,serial
• for partition UUID, I check /dev/disk/by-partuuid to get the partition device
• to get the disk device from a partition device, I just remove the trailing digits (/dev/sde2 -> /dev/sde)

I have just rebased my branch to master to simplify the merging.

Changing argv value is not a good practice. Can we just switch the code below (where argv[1]) is used to use of disk_device?

Basically:

    disk_device = find_serial( argv[1] )  # by serial number
    if not disk_device:
        disk_device = find_disk( argv[1] )  # by /dev/disk/
    else:
        disk_device = argv[1]

(and replace all uses of argv[1] with disk device).

Do you want to support regexps? How do you plan to use it? sdled s.+z?

May be we can just check for case-insensitive match?

Suggested change

	absolute_device_path = re.sub("\d+", "", absolute_device_path)
	absolute_device_path = re.sub(r"\d+", "", absolute_device_path)
