Spider spawns unnecessarily many system threads for stats synchronization

Details

    Description

      Spider spawns 10 stats synchronization system threads per statistics by default. This seems to be too much for many use cases and unnecessarily many threads complicate debugging.

      Set the default values of spider_table_crd_thread_count and spider_table_sts_thread_count to 1.
