Better encryption and easier database test

### The required feature described as a wish

As a user I would like to have better encryption and, above all, to be able to perform quick tests without the complexity of setting up traditional databases, so I think it would be a good idea to implement JWT and SQLite in Cloudstack.

JWT could be implemented to improve the way in which users like me or applications access the API, as it uses user/password credentials, as well as a token that expires according to a stipulated time. JWT would be very easy to implement in Cloudstack.

SQLite does not require a dedicated server, which would make Cloudstack less resource-intensive and easier to configure, as well as allowing for rapid prototyping and testing.

Es sind keine Quelldateien, Tests oder Einstiegspunkte identifiziert. Beginnen Sie damit zu klären, ob die JWT-Authentifizierung und die SQLite-Unterstützung beide im Umfang enthalten sind; der Abschluss würde explizite Anforderungen und eine Validierung für jedes vorgeschlagene Feature erfordern.
