Calculate best AttributeCombination for Discovery

Currently users have to start a discovery with fixed SearchAttributes. This means users have to calculate / know the best attribute combination for their started discovery. Often this will not be the case and can easily become quite complicated with multiple attribute combinations and attributes set as wildcard.

Therefore the SkABNetNode provide the functionality to calculate the best Attribute Combination for a given AttributeMap with filled values. The resulting SearchAttributescan then be used to start a discovery.

By seperating these steps users can still manually define SearchAttributes for a discovery or store / manipulate the calculcated SearchAttributes.
