add podman and docker binaries

In ansible#22 and ansible#23 the podman and docker molecule drivers were added,
but the respective binaries are still missing.

This commit adds the necesarry dependencies to the execution
enviroments bindep.txt.

This commit also adds some CLI commands to check we do not remove
them inadvertently and output some helpful version information at
build time.
