[Feature Request] Take password during first setup instead of creating user without one.

[Maxwelldoug]

Would it be possible to move the prompt for setting the user's password into first-setup? With the current setup, creating a user with a non-existant password and marking it as expired (equivalent to running passwd -de), GDM is the only display manager I've tried that doesn't break entirely. This change would be very useful for pretty much all my images, allowing the addition of SDDM to Kanola, qtgreet to Hoisin, tuigreet to Lime, and more in the future.

This would also bring our procedure more in line with what every other distro on the market does, as I have seen confusion from users on this approach, both in how it works and why we do it.

I support this proposal.

Great care needs to be taken to guarantee security though. (The password should be passed via stdin for example to make sure it doesn't leak)
