Sharding need special storage driver wrapper for queue-related operations. The listing queue algorithm merges the listing result from multiple storage connections, and return them in sorted order. This patch also fixes non-configurable default limits in sharding. Change-Id: If9bd80459bd1a0dc92ea68c42bc28c0f6dde2a65 Partitally-implements: blueprint storage-sharding
