    urlPreview: Do not generate thumbnails on metered connections
    
    When the network connection is metered, we should avoid any
    non-essential traffic. That certainly applies to URL previews,
    so treat metered connections the same as no connectivity and
    delay thumbnail generation until we get unmetered network access.
