foreign-menu: Check if storage domain is active for data center
    
    This last patch of the series is where we actually check if the storage
    domain is active in the data center the VM is associated with. It makes
    use of g_strv_contains(), which is available only in glib version 2.44.
    Compatibility code has been added if building against older versions
    than required.
