`simp config` should have a way to generate a privileged user to login to the system

Currently, `simp config` fails at the end of a successful run because it has deemed the system unsafe and might prevent the user from logging in after bootstrap. In addition to a quick start install mode (see linked ticket) there should be a way to have `simp config` create a user and create some basic sudo rules and PAM rules to allow them to login (perhaps a user called simp). While this may not be desired in a production setting, it would be tremendously helpful for users just getting started who might not be familiar enough with SIMP/Puppet to properly digest the information in the bootstrap lock file.
