Feature Request - Enable prompt for user creation during workflow, akin to computer naming

[Allister Banks]

Ideally, when configured, workflow would kick off and

1. from recovery, pop dialog requesting user info

2. if a local artifact (plist/json config) is present, use that to auto-create (I don't think that's possible with a config profile except via DEP, and not sure if sysadminctl is the 'better' way to have user creation occur on firstboot... 🤔)

3. otherwise allow username/password entry

4. for great justice!!!!!1!OMGWTFBBQ kick off filevault to end user

As I already have a library-ized scripted way to create a user that I'd pull in from the env variables implemented in #129, at the very least the priority on this can be lowered

has justice been served?
