Fixes https://github.com/kubernetes/kubernetes/issues/36007 .
This removes the special casing for TPRs inside of the `UnstructuredObject`, which should allow CRUD against skewed kube api server levels.

fix leaking memory backed volumes of terminated pods
Currently, we allow volumes to remain mounted on the node, even though the pod is terminated. This creates a vector for a malicious user to exhaust memory on the node by creating memory backed volumes containing large files.
This PR removes memory backed volumes (emptyDir w/ medium Memory, secrets, configmaps) of terminated pods from the node.

Node E2E: Remove kubelet related flags
This PR:
1. **Add `KubeletConfig` in test context.** The configuration is dynamically retrieved from kubelet `configz/` endpoint after test node registers itself.
2. **Change tests to look at `KubeletConfig` instead of other kubelet related fields in test context.**
3. **Remove kubelet related flags from node e2e.** Add `kubelet-flags` to pass kubelet flags all together.
Why do we need this change?
1. This is required by **node soaking test and node conformance test**.
* **For node soaking test.** We'll have one job start the test environment, and another job running the actual test again and again. It's hard to tell the test by flag how kubelet is configured.
* **For node conformance test.** Kubelet is usually started by user. It's hard and troublesome to tell the test by flag how kubelet is configured.
2. **No need to add another flag in node e2e for each kubelet flag we want to set in the test.** Just directly add the kubelet flag into `kubelet-flags`.
In the future,
1. Kubelet start logic should be moved outside of the test. We should have standard kubelet launcher or standard cloud-init node setup script etc.
2. The test should validate kubelet configuration:
* Whether the configuration is production ready?
* Whether the configuration has conflicts?
* Whether some configuration conflict with node e2e/conformance test is turned on (cloud provider etc.)? (Some configurations need to be turned off when running node e2e/conformance test)
* ...

make kubectl create --edit iterate
`kubectl create --edit` is broken after #36148 merged.
`kubectl create --edit` will fail when a manifest that contains multiple resources.
I guess the root cause is that dynamic typer doesn't support a list of resources currently.
This PR makes `kubectl create --edit` iterate again as `kubectl create`.

Add clarity/retries to proxy url test
Improve one segment of the kube-proxy networking test by:
1. Retrying for 30s
2. Bucketing into 2 failure modes
3. Adding some clarity by describing the exec pod on failure
Althought 1 shouldn't be necessary, I don't think we lose anything if the kube-proxy convenience endpoint doesn't respond immediately, and if it fails for 30s straight it is indicative of something that requires attention probably within 1.5.
