Cursors cannot act as a context manager

I noticed this feature request for the MySQL Python connector, and thought it might be useful for the MariaDB Python connector as well:
https://bugs.mysql.com/bug.php?id=89113

Most Python DB-API 2.0 compliant drivers can create cursors as a context manager, like so:

with conn.cursor() as cur:

cur.execute(query)

result = cur.fetchone()

print(result)

The cursor is created and assigned the identifier `cur`, and when exiting the scope, the cursor is automatically closed.
