> Global level configurations (much like topic level) for brokers are managed by humans and automation systems through server.properties.  
> Some configuration make sense to use default (like it is now) or override from central location (zookeeper for now). We can modify this through the new CLI tool so that every broker can have exact same setting.  Some configurations we should allow to be overriden from server.properties (like port) but others we should use the global store as source of truth (e.g. auto topic enable, fetch replica message size, etc). Since most configuration I believe are going to fall into this category we should have the list of server.properties that can override the global config in the code in a list which we can manage... everything else the global takes precedence.
