Title:
  [UIFe] No UI indication for fingerprint enrolling progress, no way to
  enroll multiple fingers

Status in OEM Priority Project:
  New
Status in gnome-control-center package in Ubuntu:
  In Progress
Status in gnome-control-center source package in Focal:
  In Progress

Bug description:
  There is no progress information shows to user while enrolling fingerprint if 
the number of required enrollment steps is greater than 10.
  It might confuse user thinking it as freeze failure.

  Also it's not possible to enroll more than one finger.

  steps:
  1. enroll fingerprint in gnome-control-center
  2. click 'Next' on the enrolling page
  3. There is no message tell user that it need at least 12 times touching 
fingerprint.
  4. user press fingerprint for 5 times, there is no way to cancel enrolling.
  5. user wait for timeout and get error message for timeout notification.
  6. after 5. user page of setting will always failed and show no user found.

  And this also introduce some critical issue of step 6 that user page
  in settings failed forever.

  However if the enrollment succeeds:
  7. If trying to add a new fingerprint, the user is forced to delete its 
enrolled prints

  So, the suggestion would be:
  1. remind user to press 12 times on fingerprint for step 3.
  2. show the progress during user pressing fingerprint for step 4.
  3. Allow to enroll more fingers

  As per this, GNOME design has produced some artwork that we want to implement 
to fix all these issues:
   - https://gitlab.gnome.org/Teams/Design/settings-mockups/-/issues/18

  There will be few new strings, although most of the action events are
  already covered by the fprintd translations.

  UI will change quite a lot, but the current documentation [1] should
  not be affected by the change, being quite generic, but in case it
  might be updated to be clearer.
