Database clean commands

[jamesreprise]

Problem to Solve

Previously, we've had functions to clean the database via the Console. From the docs:

Cleaning a Database

Cleaning the database, not to be confused with deletion, wipes out both the data and the schema contained within the database. We can clean a database via TypeDB Console.

We don't support this currently.

Current Workaround

To clean the database, define an empty schema and delete all data via queries. To clean the data from a database, delete all data via a query.

Proposed Solution

Provide a function on Database that automatically performs the cleaning functions.
