  to bea5027a7f59bffee2a6ed931e63c05a9fb1bdc7
  - Merge "KuD cleanup script."
  - KuD cleanup script.

    This script offers means to cleanup, Docker and
    Ansible and their configurations.
    Updated the script to use docker go templating as
    opposed to regex for docker operations. Further
    modified the script to include if/else for
    docker operations for better code readability.
