Automate vizlib-server for Qlik SaaS

I would like to remove the configuration from docker-compose and get them into a first-configuration-setup done via the webpage.

That would remove passwords from the docker-compose file and make multi-tenant deployment smoother and also increase security (since no passwords are displayed in the text file)

These values:
      VIZLIB_VMC_USERNAME: "admin"

      VIZLIB_VMC_PASSWORD: "***********"

      VIZLIB_DATABASE_URL: "postgres://sa:***********@postgres:5432/collaboration"

      VIZLIB_SERVER_LICENSE: "PUT YOUR LICENSE HERE"
