source: add ability to select source in autoinstall
The source autoinstall section now supports the "id" field where the user can supply the ID of a source, e.g., "ubuntu-server" or "ubuntu-server-minimal". If the field is not supplied, the installation will use the source declared default: true (if any) in the source catalog. Otherwise, it the first source declared will be used.
