Defines a collection of Cloud Spanner keys and/or key ranges. All the keys are expected to be in
the same table or index. The keys need not be sorted in any particular way.
If the same key is specified multiple times in the set (for example if two ranges, two keys,
or a key and a range overlap), the Cloud Spanner backend behaves as if the key were only
specified once. However, the KeySet object itself does not perform any de-duplication.
Creates a key set containing a single key. key should contain exactly as many elements
as there are columns in the primary or index key with this this key set is used.
