Description

This pull request includes several changes to improve the handling and management of persistent cache tasks and peers in the project. The most significant changes involve the addition of new methods for managing persistent peers, the removal of the ReplicaCount field from tasks, and updates to various functions to handle the new structure.

Improvements to Persistent Cache Management:

• pkg/redis/redis.go: Added PersistentPeersNamespace constant and the MakePersistentPeersOfPersistentCacheTaskInScheduler function to handle persistent peers. [1] [2]
• scheduler/resource/persistentcache/peer_manager.go: Updated Store and Delete methods to manage persistent peers and set expiration for persistent tasks. [1] [2]

Task Structure and Management:

• scheduler/resource/persistentcache/task.go: Removed the ReplicaCount field from the Task struct and updated the NewTask function accordingly. [1] [2]
• scheduler/resource/persistentcache/task_manager.go: Added methods to load current replica counts and updated the Load method to reflect the new task structure. [1] [2] [3] [4]

Service Updates:

• scheduler/service/service_v2.go: Updated methods to handle the new task structure and to log errors more effectively. Added functionality to manage persistent replica counts. [1] [2] [3] [4] [5] [6] [7] [8]

Dependency Update:
