Fix default Kafka configuration for StreamWorkManager

When using the StreamWorkManager implementation with Kafka, the Kafka is configured with the default LogConfig:

kafka.max.poll.interval.ms=60000
kafka.request.timeout.ms=65000
kafka.max.poll.records=5

This will not work for a slow worker like OrphanVersionsCleanupListener which requires more than one minute on medium/large repository.
The consequence of this misconfiguration can result in blocking completely the worker pool.

A quick fix is to change the default Kafka config to use a higher poll interval like 60min.

The Stream WorkManager may need a dedicated Log Configuration (and Kafka configuration) this will be handled in a dedicated ticket.
