Add the choice of interface for keystoneclient

1. When functest is running on external host not jumpserver,
   keystoneclient is used to retrieve or create projects/tenants
   and users, which would fail to establish connection to the admin
   endpoint.
2. Keystoneclient will connect to the public endpoint by setting the
   env OS_INTERFACE to be public.
3. Remove the admin endpoint check in check_os.sh.
