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.
