In these changes, the PikaServer class has been updated to improve clarity and accuracy in slot management processes. The primary focus was renaming bgsave_protector_ to bgslots_protector_ to better reflect its role. Furthermore, the related slot operations were adjusted and conditioned checks were refined. This ensures better code readability and synchronization in background slot management.

In the server's code so bright, Slots are managed with delight. Renamed to protect and reload, Ensuring data flows in a constant mode. With
bgslotsguards standing tall, PikaServer now heeds the performance call.

这里是为了bgsave和slots cleanup相互制衡，但是使用了 pika server中的bgsaveinfo，但是pika_server中的bgsave_info_没有赋值，应该使用 DB中的，考虑到codis slot迁移只能支持一个DB这里暂时没有考虑多DB 场景
