BREAKING CHANGE: Users have to modify their pillar
according to this commit. Users MUST append '.conf' for their

BREAKING CHANGE: all previous `nginx` based configurations must be reviewed;
`nginx.ng` usage must be promoted to `nginx` and any uses of the original
`nginx` will have to be converted.
