Kiali ready to be updated - need some PRs merged

For Istio master, we would like to bump up to the latest Kiali release of v0.16.

I created a PR to do this. If you want to review, see https://github.com/istio/istio/pull/11823

I need an approver to review and merge that PR.

Note also we have a PR to add basic e2e testing for the Kiali add-on. Can we get an approver to take a look and merge that, too? All required tests are passing - see: https://github.com/istio/istio/pull/11448
