It appears that this will be fixed in a future version of Kafka (it will no longer pass through "unrelated" configs when parsing this): https://issues.apache.org/jira/browse/KAFKA-10090
In the meantime, we should be able to turn those to ERROR or something, and make a note to change it back when we upgrade to 2.8 or higher.

SCENARIO:
Minions setup to use Kafka are generating multiple warning logs every 5 seconds during health-check.
The felix.fileinstall.filename and service.pid logs are generated with a vanilla configuration. Additional kafka rpc and ipc settings defined in minion-config.yaml also trigger this warning log (ex: single-topic).
Seen with minion 27.0+.
Hopefully just log noise that still should be either fixed, downgraded from WARN or silenced.
Even if just log noise, we should either fix, downgrade or silence
