    openqa: try and fix on-disk encryption stuff
    
    Some of the openqa workers are encrypted and some aren't (this is a bit of a
    mess that's partly a result of all the redeployments we did around
    https://bugzilla.redhat.com/show_bug.cgi?id=2009585 ). We should only run
    the nbde_client role on workers which are encrypted. Hopefully this gets that
    right.
