+1 on the verification done by Frank: I did a couple of non-s390x
installs using the -proposed ISO and everything looks good.

Bug description:
  [impact]
  cloud-init no longer puts the password of a user with a RANDOM password anywhere subiquity can find it, so while the password chosen ends up printed to the console, subiquity cannot display it from within the UI as it used to.

  [regression potential]
  If something goes wrong here, it's possible that subiquity will no longer be able to display the password for the installer user at all, which will make continuing the install via SSH impossible (this is very important for installing on z/vm)

  [test case]
  Make an ISO with this change and boot it and check that the installer password is available in the UI. Make a s390x ISO, boot it in z/vm and check that the installer password is displayed on the console.

  [original description]
  Using the latest Impish daily ISO (timestamp) 2021-06-24 I faced the situation that I didn't got a temporary installation password not the key fingerprints at the end of the installer boot-up process.

  Hence I am not able to perform an installation from remote via ssh.
  However, subiqity is started at the console (e.g. Integrated ASCII console) and an installation can be successfully completed there, but a console installation is not in all cases possible, for example with z/VM guests.

  As one can read between the lines I tried this on s390x (Integrated
  ASCII console and z/VM), but 'paride' tried the same on amd64 and ran
  into the same symptoms, so it does not seem to be architecture
  specific.

  This must have happened recently, since I already was able to do ssh-based Impish installations on s390x in the past (for example with the daily ISO from 06-14-2021).

  This is not the case for the 20.04 dailies - I can do remote ssh installation with the 20.04 live daily ISOs.

  With Impish on s390x the kernel parameter 'quiet' is still set by
  default.
