Support running license scan independently

[shahar-h]

Currently license scan (--experimental-licenses flag) runs along with vulnerabilities scan. In our case we want to run vulnerabilities scan recursively(with -r flag) but license scan should be run only on root folder.
Adding support for running only license scan will help.
Other option is support a dedicated recursive flag for license scan.
