Modin 0.6.0 release notes

This release contains a large number of internal changes and some new functionality. Notably, a Dask backend for Windows support was added, and the pandas version was updated to 0.25.1. There were a number of minor bugfixes as well. The entire backend was refactored in #721 to support future additions easier and query planning.

We also dropped Python2 support while updating to the newest pandas version. pandas is no longer supporting Python2, so we will not as well.
