  - Add scripts to setup ONAP on OpenStack

    JIRA: Auto-5

    Setup ONAP environment on OpenStack. Develop Using
    Python considering its proved performence within
    OPNFV testing project, and with its rich library we
    can operate REST calls and json parsing in a more
    elegant way, also others can reuse the existing
    module to develop use cases and test cases.

    Main workflow:
    1. prepare OpenStack to launch ONAP (images, security
    rules, keypair, etc)
    2. launch ONAP stack
