Fix e2e test cleanup.

E2E test should use `AfterEach` instead of `AddCleanupAction`.
`CleanupAction` only runs once after all tests finish https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L258.

I hit this issue very frequently that once `Aggregator` test fails, all following tests all fail because the cleanup function does not run after the test, and namespace controller stops working with full of errors:
```
unable to retrieve the complete list of server APIs: wardle.k8s.io/v1alpha1: the server could not find the requested resource
```
