Fix recycler pod deletion race.
We should use clone of recycler pod template instead of reusing the same
one for two or more recyclers running in parallel.
Also add some logs to relevant places to spot the error easily next time.

When finishing a rolling update, a message is shown :
'Renaming oldRc to newRc'
In my case that'd be:
'Renaming nginx to nginx-df8d9fafc5007d83968cd37c8353d52e'
That naming order is incorrect, as the new name is temporary, and the final name should be the old one

remove TPR registration, ease validation requirements
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.

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`.
This PR is to fix the issue in converting aws volume id from mount
paths. Currently there are three aws volume id formats supported. The
following lists example of those three formats and their corresponding
global mount paths:
1. aws:///vol-123456
(/var/lib/kubelet/plugins/kubernetes.io/aws-ebs/mounts/aws/vol-123456)
2. aws://us-east-1/vol-123456
(/var/lib/kubelet/plugins/kubernetes.io/mounts/aws/us-est-1/vol-123455)
3. vol-123456
(/var/lib/kubelet/plugins/kubernetes.io/mounts/aws/us-est-1/vol-123455)
For the first two cases, we need to check the mount path and convert
them back to the original format.

Handle Empty clusterCIDR
**What this PR does / why we need it**:
Handles empty clusterCIDR by skipping the corresponding rule.
**Which issue this PR fixes**
fixes#36652
**Special notes for your reviewer**:
1. Added test to check for presence/absence of XLB to SVC rule
2. Changed an error statement to log rules along with the error string in case of a failure; This ensures that full debug info is available in case of iptables-restore errors.
Empty clusterCIDR causes invalid rules generation.
Fixes issue #36652
We have observed that, after failing to create a container due to "device or
resource busy", docker may end up having inconsistent internal state. One
symptom is that docker will not report the existence of the "failed to create"
container, but if kubelet tries to create a new container with the same name,
docker will error out with a naming conflict message.
To work around this, this commit parses the creation error message and if there
is a naming conflict, it would attempt to remove the existing container.

CRI: Clarify User in CRI.
Addressed https://github.com/kubernetes/kubernetes/pull/36423#issuecomment-259343135.
This PR clarifies the user related fields in CRI.
One question is that:
What is the meaning of the `run_as_user` field in `LinuxSandboxSecurityContext`?
* **Is it user on the host?** Then it doesn't make sense, user shouldn't care about what users are on the host.
* **Is it user inside the infra container image?** This is how the field is currently used. However, Infra container is docker specific, I'm not sure whether we should expose this in CRI.
* **Is it the default user inside the pod?** It tells runtime that if there is a container (infra container, or some other helper containers like streaming container etc.), if their `user` is not specified, use the default "sandbox user". Then how can we guarantee that infra or helper container image have the `user`?
* **It doesn't make sense?** If we remove it, we are relying on the shim to set right user (maybe always root) for infra or helper containers (if there will be any in the future), I'm not sure whether this is what we expect.

V2resource fixes
when using kubectl set resources it resets all resource fields that are not being set.
for example
$ kubectl set resources deployments nginx --limits=cpu=100m
followed by
$ kubectl set resources deployments nginx --limits=memory=256Mi
would result in the nginx deployment only limiting memory at 256Mi with the previous
limit placed on the cpu being wiped out. This behavior is corrected so that each invocation
only modifies fields set in that command and changed the testing so that the desired behavior
is checked.
Also a typo:
you must specify an update to requests or limits or (in the form of --requests/--limits)
corrected to
you must specify an update to requests or limits (in the form of --requests/--limits)
Implemented both the dry run and local flags.
Added test cases to show that both flags are operating as intended.
Removed the print statement "running in local mode" as in PR#35112
The original PR associated with these fixes where reverted due to causing a flake in hack/make-rules/test-cmd.sh, I gave the 'kubectl set resources' tests there own deployment and set the terminationGracePeriodSeconds to 0 and have run test-cmd.sh for hours without hitting the flake
