Use ResourceLoader to ingest compose files

[Mjaethers]

Related to PR #555 and Issue #554

To achieve consistency in the way resources are loaded for docker compose the config files are now ingested via ResourceLoader. For local files the existing localResourceLoader is used.

To add new ways of loading compose files in the future a new ResourceLoader should be implemented and added to the project options.
