Thanks Eduardo, I did a mistake by pulling prebuilt 2.0.2 images from Docker hub.
Obviously 2.0.2 build is broken as Ansible shipped with this doesn't have required OpenStack modules.
Building 2.0.3 images by myself fix the problem and 2.0.3 deployment is smooth.
Thank you very much for your support!
