Motivation: docker-sync.io helps to speed up docker FS access on macOS and so make builds there a lot faster. We should add some config to help users use it. Modifications: Add docker-sync configs for centos-6.18 which is what we use for releases. Result: Faster builds via docker and when using macOS possible.
Using the docker images
