yes using v0.17.6 but i think because of knative pkg version change there is some changes in generated clients

[dibyom]

I think this version also adds leader election capability so we might have to call Promote in any tests that create a reconciler:

@tektoncd/triggers-maintainers so in the future, it would be nice if each triggers release would bump to the latest tektoncd/pipeline version available at that time 😛
