Add smoke test for helm deployment

[bstadlbauer]

This PR adds a smoke test that installs the helm chart into the local kind cluster to check whether the deployment is working correctly and a simple cluster can come up. This should minimize releasing broken versions.

@jacobtomlinson Seems like the test setup is slow and I would expect this to be due to the docker build that's happening.

Should I try to improve the build time there by leveraging caching?

I've also added a second tests with --set=rbac.create=false which seems to be failing - is this expected? (we're not using this internally, but that's what was used in the original issue #749)

I'm curious why the existing docker image fixture isn't being used here?

We should look into this. Do you want to xfail the test for now and open an issue to track it?

Closing this as I've had not had time to get back to this
