Need additional Kafka Producer/ConsumerConfig parameters exposed

[kdunn926]

I'm building a custom splitter processor module with reasonably large records and am hitting this exception:

org.apache.kafka.common.errors.RecordTooLargeException: The message is 1125040 bytes when serialized which is larger than
the maximum request size you have configured with the max.request.size configuration.

I've adjusted the max.request.size parameter on the Kafka server configuration although it looks like the Kafka Binder can override this setting on the client side. In my stdout logs below, I see max.request.size = 1048576 regardless of the server setting.

        key.serializer = class org.apache.kafka.common.serialization.ByteArraySerializer
        retries = 0
        max.request.size = 1048576
        block.on.buffer.full = true
        value.serializer = class org.apache.kafka.common.serialization.ByteArraySerializer
        metrics.sample.window.ms = 30000
        send.buffer.bytes = 131072
        max.in.flight.requests.per.connection = 5
        metrics.num.samples = 2
        linger.ms = 0
        client.id =

Any chance we can expose this parameter to the Producer and Consumer clients, similar to this:
spring.cloud.stream.kafka.binder.fetchSize

Thanks!
