Implement lru_cache CacheManager

[Johnny850807]

I am not sure about what use cases and what "many more fueatures" will be included in this decorator.
But please also have a look at from functools import lru_cache

#bn

I don't know either, maybe this is a moment that I need your suggestion! I will take a look at lru_cache thanks!
