following 3rd party integration with tcib fails

[Alex Schultz]

Following the 3rd party integration docs results in failures as we assume there is always a tcib directory in the config path and the config path top level directory is incorrectly hardcoded to be 'container-images'

    Fix tcib build

    The tcib build process assumes that all the container configs exist in a
    'tcib' folder as defined via --config-path. This change documents this
    requirement and additionally we've hard coded 'container-images' in
    the image config to exclude this folder however if you define a
    custom --config-path, this fails. This change removes the hard coded
    'container-images' while documenting the 'tcib' requirement.
