ruby: reorganized ruby python configuration
Reorganized ruby python configuration so that protocol and ruby memory system configuration code can be shared by multiple front-end configuration files (i.e. memory tester, full system, and hopefully the regression tester). This code works for memory tester, but have not tested fs mode.
