AutoTuner test recommendations need to be isolate from the Profiler

[amahussein]

Is your feature request related to a problem? Please describe. Following up on #6300 , the Autotuner code should be refactored in a way to enable testing recommendations based on existing calculations. Currently, we need an entire eventlog to be passed as argument to the Profiler. This makes it hard to test the configurations separately because the eventlog will drive the calculations.
