> inter.broker.protocol.version configuration was nice for few releases, but it is getting to be a pain to maintain, remember to update, it breaks on trunk upgrades, etc.
> Since we have KIP-35, the controller can actually check for specific versions supported by brokers for specific API requests. Why not use that and get rid of the configuration? 
> We already maintain the protocol versions anyway, upgrades will be smoother, and we'll support upgrades between any two patches.
