Allow to host .circleci.yml configuration externally
I’d like to keep repository free from CI configuration noise.
e.g. Appveyor CI allows to provide an URL to YAML config on project settings in Appveyor GUI.
It’s great also for other reason, as that way I can easily share common config among projects that require same setup.
Is there any way to achieve that with Circle CI? If not, is it somewhere on a roadmap?
