Backend: Create database for the annotations

[MercerFrey]

Description:

Annotations should be stored in another database because we will use Web Annotation Data Model. In the future, internet users other than Heka users would want to access this database or use this annotation service. Creating another database is mandatory for the annotations.

Steps:

1. Create another database with the Docker.
2. Connect the database with the Django backend.
3. Create this database on the test server.
