* removes costly json serialization to InMemoryCacheAdapter
* Always cache a copy of the array
* Use own mapValues
* Makes sure we dont make unnecessary calls to the logger
* Do not bypass loggers with silent logging (only applies to stdout)
* warn is not warning
* use ===
* Wrap logRequest / logResponse in the loggerController for more granular control
Also give the ability to pass functions to the logger so we don't serialize too early in JSON (costly)
* reconfiguring winston would override the transports levels and make subsequent tests fail
