installer image should always give you the option to get a root shell for debugging

[Steve Langasek]

On d-i and ubiquity installer images, the user can always switch VTs to get a prompt that reads (paraphrased from memory): "Press ENTER to get a shell". We should deliver the same experience on subiquity images.

Currently, when booting a subiquity image, changing VTs gets me an additional instance of subiquity running. This does not help me for debugging the one I've already got running. ;)

If modifying subiquity to not take over >1 VT means that we get a getty, and we have some l/p info that we can use to log in as root, that is a reasonable first pass on this to unblock debugging of running images. But ultimately the experience should be 'press enter'.

FTR, the wording used by d-i is "Please press Enter to activate this console."

---------------
subiquity (0.0.27) zesty; urgency=medium

  * Many fixes to get subiquity operational again.
  * Fix header of WIFI config screen (LP: #1651119)
  * Fix partion size rounding to correctly round to 1M boundaries, not 1G.
  * Improve widget used to select filesystem type. (LP: #1654387)

    (LP: #1654381)
  * Make a cleaner separation between console-conf and subiquity code.
  * Remove lots of unused code.
  * Make installprogress controller (the code that drives curtin) more event
    driven, removing polling and the dependency on python3-tornado.
  * Make the curtin log viewer much more intuitive. (LP: #1654390)
  * Rearrange subiquity's systemd units to allow running a root shell for
