Jan Chaloupka 6e953b2ff3 Separate migration of strategy configuration from the constructing and running the plugins (#999)
* Remove log level from Errors

Every error printed via Errors is expected to be important and always
printable.

* Invoke first Deschedule and then Balance extension points (breaking change)

* Separate plugin arg conversion from pluginsMap

* Seperate profile population from plugin execution

* Convert strategy params into profiles outside the main descheduling loop

Strategy params are static and do not change in time.

* Bump the internal DeschedulerPolicy to v1alpha2

Drop conversion from v1alpha1 to internal

* add tests to v1alpha1 to internal conversion

* add tests to strategyParamsToPluginArgs params wiring

* in v1alpha1 evictableNamespaces are still Namespaces

* add test passing in all params
