Some classes require nova::compute::libvirt but there is no need to put that class into dependencies because resource orders are defined by deps or explicit definitions. Also, the base libvirt class is not really required. This change removes these dependencies, to avoid enforcing orders as much as possible. Change-Id: Icbb2fa209effd355cef36f35662bfdcf18d8b090
