FIX: Handle NonSupportedFeature exception for pipes (#660)

* Old tango servers don't support the pipe API when used with PyTango versions less than 9. Since we don't support pipes yet anyway, we should handle this exception and move on.

* Fixed linting. NonSupportedFeature is not a recognizable import symbol because of something in pytango so type checking needs to ignore it.

* Trigger CI/CD pipeline
