add two new query types, namely <code>TimestampedKeyQuery</code> and
<code>TimestampedRangeQuery</code>. Both should be used to query a timestamped
key-value store, to retrieve a <code>ValueAndTimestamp</code> result. The
existing <code>KeyQuery</code> and <code>RangeQuery</code> are changes to
always return the value only, also for timestamped key-value stores.
