[backend] add exclusion cache handling (search tree version) (#8941)

[JeremyCloarec]

Proposed changes

• add cache file containing local exclusion list cache tree
• add cache init at start of platform, reading current cache from redis if it exists
• add cache build manager, building new cache when an exclusion list is changed and pushing it to redis
• add cache sync manager, reading cache status on redis and updating local cache if it is outdated
• add search algorithm to check if a value is in current cache tree
