This reproduces the helm issue at helm/helm#1873.
It performs three helm upgrade commands each changing the readinessProbePath.
- sets readinessProbePath to '/'. This passes.
- sets readinessProbePath to '/bad-path'. This fails as expected.
- sets readinessProbePath to '/'. This should pass but fails.
- kubernetes 1.8.3
- helm 2.7.2 or 2.8.0
