Title: Relocated the scope for common docker settings

I found myself forgetting the configuration in `dockerExposedPorts in Docker` and so I thought that the `dockerExposedPorts` and `dockerExposedVolumes` shouldn't need the configuration provided. The other commonly used keys do not e.g. `dockerBaseImage`.

In addition I've provided a scripted test for checking the `EXPOSE` value.
