  - k8s: Add virtual environment for testing

    This patch adds simplified ONAP deployment environment (Kubernetes
    cluster managed by Rancher). Its purpose is to provide cluster defaults
    for inspection without the need to access actual ONAP application
    deployment.

    Default node customization scripts were extracted
    ("tools/get_customization_scripts.sh" run within "tools/imported/"
    directory) from official documentation [1] and imported here in order
    not to introduce runtime online dependencies.

    This environment should probably be migrated in future to more
    appropriate place like devtool [2] (or at least use the same Vagrant
    boxes).
