feat: added LRU cache for mockDB connections (#36480)
## Description
This PR implements an LRU (Least Recently Used) caching mechanism for
the Mongo mockDB connections which get auto-cleaned up every 2 hours
based on their access time.
This is done to stop the overpopulation of the open dangling connections
to the mockDB resulting in the max connection limit.
The Caching Implementation used is [Google Guave
Cache](https://github.com/google/guava/wiki/CachesExplained).
