Allow updating default DBus timeout on every interface
Summary:
Some methods in the ModemManager API (e.g. network scan) may take
longer to complete than the default DBus timeout configured for the
QDBusAbstractInterface, which is 25s usually.
Allow clients to update this default timeout on every interface.
