From: Chen Qi <qi.c...@windriver.com>
This class is dedicated to image level user/group configuration.
It inherits useradd_base.bbclass.
Users need to inherit this class in their layers or local.conf to
make the setting of EXTRA_USERS_PARAMS effective.
For detailed configuration format of EXTRA_USERS_PARAMS, please
refer to local.conf.sample.extended.
