Review comment:
committing offset to Kafka is optional for the user, failure of single
commit should not fail the complete job, hence logged this exception.

Review comment:
Are you proposing to create `KafkaOffsetGen` object in `DeltaSync` as
well to call `commitOffsetToKafka` method ? I wanted to avoid doing it as we
are already doing so in respective Source classes. Also, I saw
`excludeHoodieConfigs ` as helper method, hence created static

Review comment:
make sense, updated code, did not rename
`hoodie.deltastreamer.kafka.source.maxEvents` in this PR, will discuss more on
compatibility
