Remove max version restriction for Dask/Distributed

[charlesbluca]

In advance of our next release, removes the max version restriction for Dask/Distributed so that we can check for potential compatibility issues (specifically those raised in #350 since dask-ml hasn't cut a release since @ayushdg's fix)

Thanks for these changes. I suspect things will work now since dask hasn't cut a release since the changes that broke dask-ml merged in. But I believe the dask community is planning a release sometime this/next week and I suspect we'll see some failures seen in #350 until a dask-ml release.
