feat: add support for search queries with a GSI/LSI index

[sndpl]

This PR adds support for pagination when searching with a GSI/LSI index.
The lastEvaluated key contains the following depending on the kind of query you perform:

• a normal search only the primary partition key and primary sort key are part of the lastEvaluated key.
• a query on GSI, then the LastEvaluatedKey will be the compose of GSI partition key, GSI sort key, primary partition key and primary sort key.
• a query on LSI, then the LastEvaluatedKey will be the compose of LSI sort key, primary partition key and primary sort key.
