environment variable and volume

This test creates two containers both of which are running flask. The first container has an environment variable called PODMAN_MSG. That container pipes the contents of PODMAN_MSG to a file on a shared volume between the containers. The second container then reads the file are returns the PODMAN_MSG value via flask (http).
