Configuration to resolve environment variables via ${env.VARIABLE} references

      Description

      We should be able to get env variables from Configuration files, rather than just system properties. I propose using the traditional env prefix ${env.PATH} to make it immediately clear to people reading a conf file that it's an env variable -and to avoid any confusion with system properties and existing configuration properties.
