1. Cleanup the user creation so that the distro class is

responsible only for creating users and groups and
normalizing a input configuration into a normalized
format that splits up the user list, the group list
and the default user listsand let the add user/group config 
module handle calling those methods to add its own users/groups 
and the default user (if any).

2. Also add in tests for this normalization process to ensure
that it is pretty bug free and works with the different types
of formats that users/groups/defaults + options can take.
