KAFKA-4064 Add support for infinite endpoints for range queries in Kafka

being inclusive to get meaningful tests to work.

>
> In some applications, it's useful to iterate over the key-value store either:
> 1. from the beginning up to a certain key
> 2. from a certain key to the end
> We can add two new methods rangeUtil() and rangeFrom() easily to support this.
