  - automated configuration of an OpenStack instance for ONAP

    Initial code (based on OpenStack SDK Python client) for configuring
    an OpenStack instance (e.g. installed by Fuel/MCP) and prepare it for
    ONAP (especially, to host VM-based VNFs).

    Currently works: creation of networks, routers, router interfaces,
    security groups (accessing VMs also works with compute proxy, but is
    not used for this program).

    Current issues: identity proxy (so can't create projects and users),
    adding gateway to router, deletions

    This script could be launched automatically right after installing
    OpenStack, and before installing ONAP (so as to grab OpenStack info
    to be fed into ONAP configuration files). Also, VNF YAML/ENV files
    can be populated once the OpenStack instance is ready for ONAP.

    Note: plenty of test and debug lines, which would be removed.
    This changeset is just to capture a snapshot of this effort in the
    Auto repository, and to enable reviews and feedback.
