generate db config with all clients

[Elhebert]

What does it do?

It update the project generator to generator a database configuration that relies on env variables for the database selection.

With theses changes Strapi will support database connection strings using the DATABASE_URL env variable.

Why is it needed?

This will unlock the possibility to chose your DB client on each environment without having to adapt your config/database.js

How to test it?

• Generate a new Strapi project and look at the .env and config/database.{js|ts}.
• The e2e tests should still pass as they also rely on the project generation to create a new Strapi project.
