When setting up a non-passthrough cluster aggregation, mongos establishes cursors on the targeted shards that will be used by the merging portion of the pipeline. We must ensure that, if the aggregation fails during planning, we appropriately clean up cursors and do not leak them.

As part of this work, we'll also write tests that deliberately force a failure and assert that cursors are cleaned up appropriately.
