## 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).
