Review comment:
I like that you replaced these strings (like `bootstrap.servers`) so the
compiler is more likely to catch any changes to the property names that might
be made in Kafka as part of the upgrade.
Since you already went half-way, here are the others.
* `enable.auto.commit` -> ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG
* `auto.commit.interval.ms` -> ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG
* `session.timeout.ms` -> ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG
