[ADAPTER] Apply PyMongo-like amalgamation to AstraPy, to emulate DataStax Astra DB

## Introduction

In the spirit of the PyMongo driver amalgamation, it looks like [AstraPy](https://github.com/datastax/astrapy), the Python client SDK for DataStax Astra and Stargate, based on the [DataStax python-driver](https://github.com/datastax/python-driver), has a very similar interface.
