    Ported tripleo-modify-image to py3

    It makes yum and pip installs work with py3 packages. The package manager
    dnf/yum and pip binary are determined at run time from the OS.

    Use dnf-plugins-core for dnf with respect to
    yum-plugin-priorities.

    Use pipefail with set -ex to fix linter errors.
