Refactoring datasets in SystemDS

[Shafaq Siddiqi]

Hi,

Some of the test suites in SystemDS use external data files that are 
stored in the test package along with the test files. I have observed 
that there are some test files that use the dataset residing in another 
test package such as the Iris dataset is being used by gmm and 
gmmPredict tests and it is stored inside the transform test package. The 
same is the case for the Salary dataset that is used by different test 
files.

In my opinion, it would be effective if we store all datasets inside the 
resource folder so that the existing datasets are available up-front and 
could be reused instead of introducing a new dataset every now and then 
and it will also simplify the referencing of the datasets across test 
suites.
