Adding CONTAINER_COMMANDS_ENABLE variable for container-shell to add support for allowing certain container commands for a specific container-shell invocation only.
Use case: Allow some people (via their SSH key) to only execute some
but not all commands, e.g. container start and container-stop but
not container create and container remove.
