This patch adds to Alternator an implementation of the BatchGetItem operation, which allows to start a number of GetItem requests in parallel in a single request. The implementation is almost complete - the only missing feature is the ability to ask only for non-top-level attributes in ProjectionExpression. Everything else should work, and this patch also includes tests which, as usual, pass on DynamoDB and now also on Alternator. Signed-off-by: Nadav Har'El <nyh@scylladb.com>
