Expand location templates in container_run_and_extract rule.

[k0walik]

The container_run_and_extract rule accepts list of labels as the input arguments passed to the action running the container. We could elevate this information by applying expand_templates to docker_run_flags and pass generated files (i.e. environmental variables) as the input to the shell script that executes the action.
