Quantization Cache Class Looks good , but we need to improve on unit tests for following test cases

1. testSingleThreadedAddAndRetrieve 2.testMultiThreadedAddAndRetrieve 3.testMultiThreadedEvict 4.testConcurrentAddAndEvict 5.testCacheClearFromMultipleThreads

Let's have all these tests added.

The most recent commits should address @navneet1v 's comments 1-5. Will add to stats in follow up PR. I also still need to add more unit testing for the new functionality.

There's one flaky test I'm still trying to fix. (edit: should be fixed now)
