configs,mem-ruby: Procotol-spec. names in CHI

Use the protocol-specific controller names in CHI.

**Important**: This could change some scripts. As long as people use
CHI_config (likely), this shouldn't be a problem, but if you have a
different version of CHI_config.py locally, you will need to make the
following updates:

`Cache_Controller` -> `CHI_Cache_Controller`
`Memory_Controller` -> `CHI_Memory_Controller`

Website updates coming soon!
