Kubelet flags take precedence over config from files/ConfigMaps
Changes the Kubelet configuration flag precedence order so that flags
take precedence over config from files/ConfigMaps.
See:
https://docs.google.com/document/d/18-MsChpTkrMGCSqAQN9QGgWuuFoK90SznBbwVkfZryo/
Also modifies e2e node test suite to transform all relevant Kubelet flags into
a config file before starting tests when the KubeletConfigFile feature gate is
true, and turns on the KubeletConfigFile gate for all e2e node tests.
This allows the alpha dynamic Kubelet config feature to continue to
work in tests after the precedence change.
fixes#56171
Related: https://github.com/kubernetes/features/issues/281
```release-note
CLI flags passed to the Kubelet now take precedence over Kubelet config files and dynamic Kubelet config. This helps ensure backwards compatible behavior across Kubelet binary updates.

Sts per Pod Name Label
**What this PR does / why we need it**:
StatefulSet controller will add a label for each Pod in the StatefulSet. The label is of the form
`statefulset.kubernetes.io/pod-name: <pod.Name>`. This allows a unique service to be created for each Pod in the StatefulSet.
Fixes #44103, #28660
```release-note
StatefulSet controller will create a label for each Pod in a StatefulSet. The label is named statefulset.kubernetes.io/pod-name and it is equal to the name of the Pod. This allows users to create a Service per Pod to expose a connection to individual Pods.

Initial basic bootstrap-checkpoint support
**What this PR does / why we need it**:
Adds initial support for Pod checkpointing to allow for controlled recovery of the control plane during self host failure conditions.
fixes#49236
xref https://github.com/kubernetes/features/issues/378
**Special notes for your reviewer**:
Proposal is here: https://docs.google.com/document/d/1hhrCa_nv0Sg4O_zJYOnelE8a5ClieyewEsQM6c7-5-o/edit?ts=5988fba8#
1. Controlled tests work, but I have not tested the self hosted api-server recovery, that requires validation and logs. /cc @luxas
2. In adding hooks for checkpoint manager much of the tests around basicpodmanager appears to be stub'd. This has become an anti-pattern in the code and should be avoided.
3. I need a node-e2e to ensure consistency of behavior.
**Release note**:
```
Add basic bootstrap checkpointing support to the kubelet for control plane recovery

Add Pod-level local ephemeral storage metric in Summary API
This PR adds pod-level ephemeral storage metric into Summary API.
Pod-level ephemeral storage usage is the sum of all containers and local
ephemeral volume including EmptyDir (if not backed up by memory or
hugepages), configueMap, and downwardAPI.
Address issue #55978
**Release note**:
```release-note
Add pod-level local ephemeral storage metric in Summary API. Pod-level ephemeral storage reports the total filesystem usage for the containers and emptyDir volumes in the measured Pod.

Azure Load Balancer reconciliation should consider all Kubernetes-controlled properties of a LB NSG
**What this PR does / why we need it**:
This PR refers to issue #55733
With this PR, Kubernetes will update Azure nsg rules based on not just name, but also based on other properties such as destination port range and destination ip address.
We need it because right now Kubernetes will detect the difference and update only if there is difference in Name of nsg rule. It's been working fine for changing destination port range and source IP address because these two are part of the Name. (which external users should not assume) Basically right now, Kubernetes won't detect the difference if I go ahead and change any part of nsg rule using port UI.
This PR will let Kubernetes detect the difference and always try to reconcile nsg rules with service definition.
**Which issue(s) this PR fixes** :
Fixes#55733
**Special notes for your reviewer**: None
**Release note**:
```release-note
Kubernetes update Azure nsg rules based on not just difference in Name, but also in Protocol, SourcePortRange, DestinationPortRange, SourceAddressPrefix, DestinationAddressPrefix, Access, and Direction.
