Fix compatibility with Apache Kafka 0.10.1 

Update KafkaProperties since  Apache Kafka `0.10.1` changed the type
for the `ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG` from the
`Long` to `Integer`.

Kafka includes the following conversion logic:

    case LONG:
        if (value instanceof Integer)
            return ((Integer) value).longValue();
        if (value instanceof Long)
            return (Long) value;
        else if (value instanceof String)
            return Long.parseLong(trimmed);

So we remain compatible with both `0.10.0` and `0.10.1`

Closes gh-7723
