Restore PAM user autocreation functionality (#15825) (#15867)

Backport #15825

* Restore PAM user autocreation functionality

PAM autoregistration of users currently fails due to email invalidity.
This PR adds a new setting to PAM to allow an email domain to be set
or just sets the email to the noreply address and if that fails falls
back to uuid@localhost

Fix #15702
