Description

LogisticRegressionWithSGD does not support Multi-Class input while LogisticRegressionWithLBFGS is OK.

I found this line in error
```
15/08/24 14:46:57 ERROR DataValidators: Classification labels should be 0 or 1. Found 50 invalid labels
```

In LogisticRegressionWithLBFGS there is setNumClasses method but LogisticRegressionWithSGD does not have this method.
