feat: use new kafka cluster config format

[kimxogus]

Current kafka config format is legacy format.

https://github.com/getsentry/sentry/blob/master/src/sentry/conf/server.py#L3395
https://github.com/getsentry/sentry/blob/master/src/sentry/utils/kafka_config.py#L52

I also get "Configuration property fetch.wait.max.ms (500) should be set lower than socket.timeout.ms (1000) by at least 1000ms to avoid blocking and timing out sub-sequent requests" warning log message, but fetch.wait.max.ms is not configurable too.
