Title:
  [UBUNTU 20.04] Subiquity installer does not accept user-data generated
  after manual installation

Status in Ubuntu on IBM z Systems:
  New
Status in subiquity package in Ubuntu:
  New

Bug description:
  I'm installing Ubuntu 20.04 with a nocloud-net installation source on
  a z/VM guest. I'm currently limited to seeing installation output only
  through webhook reporter, because I cannot access shell on the target
  system during installation.

  After manual installation a user-data to repeat the process
  automatically is stored in /var/log/installer/autoinstall-user-data.
  However, it has two issues:

  - there is no "version" entry, so Subiquity does not accept it at all:
  curtin start subiquity/core_validation:
  curtin finish subiquity/core_validation: 'version' is a required property

  - when I add version: 1, I get the following error:
  curtin start subiquity/Keyboard/load_autoinstall_data:
  curtin finish subiquity/Keyboard/load_autoinstall_data: None is not of type 'string'

  Failed validating 'type' in schema['properties']['toggle']:
      {'type': 'string'}

  On instance['toggle']:
      None

  And when I change this too I get the related issues with netplan and
  storage configuration.
