Tests for rolling aggregations in cudf.

[chinmaychandak]

Some features are not yet available w.r.t. rolling objects in cudf. Will update the tests once the features are rolled out.

[chinmaychandak]

This seems to failing on a test that wasn't modified. Could someone please check?

[martindurant]

Yes, appears to be due to pandas 0.25. Do you think you can fix it?

[chinmaychandak]

Made the fix, hope this works out.

[chinmaychandak]

@martindurant Some other error unrelated to the PR popped up, I guess.

[martindurant]

Please check on distributed what the correct call to gen_cluster should look like.

[chinmaychandak]

I don't think I modified that test. It seems to be a Dask-related test (is a version issue?). I'll try looking into it, although I'm not sure if I have enough knowledge to fix it.

[martindurant]

Right - it will be because the upstream signature changed in the meantime.

@martindurant Made the fixes. Could you please take a look?

Also, it would be great to have the cudf integration using conda install -c conda-forge streamz. Could one of the maintainers please update the Anaconda package; I think it is outdated w.r.t. the cudf changes?

[martindurant]

Hoping to make a release soon

Awesome, thanks!
