The listNuageVspDomainTemplat cmd was called by the ui when the create vpc dialog was opened. This command failed when no nuage vsp device was present. As a consequence the ui did not show the dialog. So currently it's not possible to create a vpc through the UI with a native CloudStack deployment. This bugfix, adds robustness to the ui that in case the cmd fails the dialog will appear nonetheless . Furthermore I also changed the listNuageVspDomainTemplateCmd to always return an empty result when there is no nuage zone.
