 Description   

Delete spider_store_last_crd, spider_store_last_sts, spider_load_crd_at_startup, and spider_load_sts_at_startup. Stats should always be retrieved when the stats synchronization is enabled.

In addition, we will refactor spider_get_share() by cutting out statistics-related processing from the spider_get_share() function. this was already done in MDEV-29676

Note that these variables controls retrieving both in-memory and persistent sts/crd, not just persistent ones.
