[Testing]

 1. Test that `ubuntu-drivers list-oem` lists the meta-package on the relevant hardware
 2. Test that fully installing the meta-package (upgrading to the OEM archive if relevant) works properly on the hardware
 3. Do an offline install. Boot the system. Run update-manager. Check that an upgrade to the OEM package is offered and that it completes successfully and the hardware works properly.

Most potential regressions will live in the package set that will be installed via dependency of this package, which live in OEM archive (outside of Ubuntu) and control by OEM team. OEM team and other corresponding team need take responsibility of those dependency installed.
