Support dockerfile_inline option docker-compose syntax

I'd like to use the dockerfile_inline option with dev containers, it currently doesn't appear to work:

      dockerfile_inline: "# syntax = edrevo/dockerfile-plus \n\nINCLUDE+ ./***/***_daemon/repo/Dockerfile-dev\nINCLUDE+

      args:

It appears to think there should be a Dockerfile somewhere when it can't find that key I think.

Reproduce the failure with the shown docker-compose.yml and the docker compose ... config command, then trace how dev containers process the dockerfile_inline build option. Done means a configuration using that option no longer attempts to open a missing Dockerfile and can proceed without that file.
