> The broker supports config overrides per listener. The way we do that is by prefixing
the configs with the listener name. These configs are not defined by ConfigDef and they don't
appear in `values()`. They do appear in `originals()`. We should change the code so that we
return these configs. Because these configs are read-only, nothing needs to be done for AlterConfigs.
> With regards to derived configs, an example is advertised.listeners, which falls back
to listeners. This is currently done outside AbstractConfig. We should look into including
these into AbstractConfig so that the fallback happens for the returned configs.
