This fixes for ruby what
https://github.com/envoyproxy/envoy/pull/3854
fixed for C#.
Description: The existing protos yield a ruby module and class with the same name for both cluster and listener. This fixes for ruby what https://github.com/envoyproxy/envoy/pull/3854 fixed for C#.
Risk Level: Low
Testing: I successfully generated valid envoy configurations using the ruby code generated by these updated protos.
