added tests for RandomForestClassifier class_weight and sample_weight & tests for KNN

[OnlyDeniko]

Added tests which are testing accuracy ratio RandomForestClassifier between Scikit-learn and daal4py on the next parameters: sample_weight, class_weight.

[PetrovKP]

We need to check every commit for these tests. for this it is necessary that these examples run during testing daal4py.

I suppose we need to check not only accuracy here by predicted labels, but additionally AUC/logloss by predicted probabilities. And probably, other metrics like F1, precision, ...
