  - Molecule container for running Molecule
    
    Add own Dockerfile and build script for creating
    customized molecule runner image from Molecule image
    provided by https://quay.io/repository/ansible/molecule.
    
    Customization enables running of molecule container with
    current host's user to avoid root owned files bloating
    to developer's machine.
    
    Add wrapper script molecule.sh to utilize custom image
    and suitable for testing offline-installer roles.
