IQv2 supports a <code>RangeQuery</code> that allows to specify unbounded, bounded, or half-open key-ranges. Users have to use <code>withUpperBound(K)</code>, <code>withLowerBound(K)</code>,
or <code>withNoBounds()</code> to specify half-open or unbounded ranges, but cannot use <code>withRange(K lower, K upper)</code> for the same.
<a href="https://cwiki.apache.org/confluence/display/KAFKA/KIP-941%3A+Range+queries+to+accept+null+lower+and+upper+bounds">KIP-941</a> closes this gap by allowing to pass in <code>null</code>
as upper and lower bound (with semantics "no bound") to simplify the usage of the <code>RangeQuery</code> class.
