[FEAT] Allow for connections to Astra DB (Cassandra)

[Chris Wilhite]

Which Datastore is this regarding?
Cassandra (or possibly a new Datastore)

Describe the solution you'd like
Astra DB is a Cassandra DBaaS. In order to connect with it, cassandra-driver needs to accept a CID/CSecret from Astra DB along with a connection payload (documented here: https://docs.datastax.com/en/astra/docs/connecting-to-your-database-with-the-datastax-nodejs-driver.html)

It would be possible to extend the current Cassandra datasource to include these driver configuration options.

Describe alternatives you've considered
Alternatively, a new Datasource for Astra DB could be added that extends the Cassandra Datasource.
