persistent naming: add ID in addition to UUID

[ilf <ilf@xxxxxxxxxxxx>]

Cryptsetup currently allows "LUKS UUID in the format UUID=<uuid>. 
Translation to real device name uses symlinks in /dev/disk/by-uuid 
directory", as quoted from man/cryptsetup.8.

Is there a reason why other persistent block device naming schemes are 
not supported? I for one would love to use by-id, "a unique name 
depending on the hardware serial number": 
https://wiki.archlinux.org/index.php/Persistent_block_device_naming#by-id_and_by-path

I am aware of the difference addressing hardware and LUKS header, but in 
my use case, I actually *do* want to address hardware in crypttab at al.

Thanks, and keep up the good work!
