Consolidate cluster aggregation targeting for passthrough/single shard queries

    Details

      Description

      Sharded aggregations currently have different code paths for unsharded collections passthrough and pipelines which only target a single shard. Conceptually we shouldn't need to distinguish between the two cases to prepare for a world where unsharded collections are tracked in the config server.
