Optimizations (#4135)

* 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
