r14790: added problem instance descriptors for miba friction datasets

TODO:

• adjust training / test paritions

r14791: fixed training / test partitions and allowed input variables

The only comment I have is that the code in the InstanceProvider.GetDataDescriptors does not make sense to me. Why is the zip file queried and then the data descriptor matched with the filename and if that succeeds the resourcename set? When i am adding a new DataDescriptor I know the corresponding resource name and can set it directly in the class. I only have to check if the resource name is present in the archive.

Code stems from RegressionRealWorldInstanceProvider.cs. Will check.
