Title:
  subiquity on s390x doesn't handle pristine DASD disks that need an
  initial low-level format

Bug description:
  In case a DASD (ECKD) disk is used for the very first time, it needs
  to be initially low-level formatted with dasdfmt (this is needed only
  once, at the very first usage).

  I found a DASD disk in my environment that was not yet used before
  (262f) and the installer should have identified that and should have
  either called dasdfmt automatically or should have provided an option
  in the menu for doing the low-level format.

  But I couldn't see any of the two options, instead I saw a crash
  saying that mke2fs failed - presumably because the disk was not low-
  level formatted before and does not have a partition with vtoc on top:

                  to re-read your partition table.

  'Format' was the only active option (that wasn't grayed out), but this
  seem to be for the Linux filesystem format only, not for the low-level
  dasdfmt.

  Btw. I used subiquity 20.06.1+git7.317648ae (1946) - used the 20.04 GA
  live installer image, but updated to the latest installer version.

  The attached doc shows the (relevant) steps I performed during the installation.
  I'll also attach the logs ...
