Python script to build and test a docker image
This script is used to generate a test report

Usage:
    docker_official_image_build_test.py --help
        Get detailed description of each option

    Example command:-
        docker_official_image_build_test.py <image_name> --image-tag <image_tag> --image-type <image_type> --kafka-version <kafka_version>

        This command will build an image with <image_name> as image name, <image_tag> as image_tag (it will be latest by default),
        <image_type> as image type (jvm by default), <kafka_version> for the kafka version for which the image is being built, and
        run tests on the image.
        -b can be passed as additional argument if you just want to build the image.
        -t can be passed if you just want to run tests on the image.
