[v4lproik]

What type of PR is this? Enhancement Bug fix

What does this PR do? Why is it needed?

• This PR does several things:
• Update the hashicorp LRU cache to the latest stable version
• Implement a better contract between caches / callers allowing homogenous code to be reused across the different types of cache (miss/hit prom metrics to be consistent, same behaviour when value not found in cache, have the same controls when inserting into the cache eg. nil value are not allowed... etc)
• Fix some bugs along the way

Which issues(s) does this PR fix? #13723
