DSE and OSS drivers unified under single DataStax driver

As of the 3.21.0 release of the Datastax Python Driver for Apache Cassandra® (OSS Driver), the Datastax Enterprise Python Driver (DSE driver) functionality has been merged into this single, DataStax driver. Please refer to the blog post <https://www.datastax.com/blog/2020/01/better-drivers-for-cassandra>_ for more information on this change.

DataStax Enterprise Python Driver

A modern, feature-rich <https://github.com/datastax/python-driver#features>_ and highly-tunable Python client library for DataStax Enterprise (4.7+) using exclusively Cassandra's binary protocol and Cassandra Query Language v3.

The driver supports Python 2.7, 3.4, 3.5, 3.6 and 3.7.
