using sysadm-general, this commit is done in preparation for simplifying
things from the following:
create zfs dataset -> create group associated with user -> manually
create the home directory -> Create the user, passing in the flags that
would have otherwise created the home directory normally, and sets the
groupID to that of the group we created before (which it should
automatically do if we don't specify a group) -> set the user password -
> enable flash -> chown the home folder over to the user
to:
create zfs dataset -> create the user using appropriate flags -> set user
password -> enable flash
usermanager backend. Brings in the following functionality:
*Create/Delete User
*Create/Delete Group
*Add/Remove User from Group
*Change a Users Password/Shell/Full Name
*Get the list of Users, Groups, and Shells
