a Return a list of devices that may contain the config drive.
The returned list is sorted by search order where the first item has
should be searched first (highest priority)
config drive v1:
Per documentation, this is "associated as the last available disk on the
instance", and should be VFAT.
Currently, we do not restrict search list to "last available disk"
config drive v2:
Disk should be:
* either vfat or iso9660 formatted
* labeled with 'config-2' or 'CONFIG-2'
