**What this PR does / why we need it**:
The tolerations printing in `kubectl descirbe pod` is not correct when toleration.value is empty, this PR is to fix it.
Before:
```
Tolerations: node.alpha.kubernetes.io/notReady=:Exists:NoExecute for 300s
node.alpha.kubernetes.io/unreachable=:Exists:NoExecute for 300s
```
After:
```
Tolerations: node.alpha.kubernetes.io/notReady:NoExecute for 300s
node.alpha.kubernetes.io/unreachable:NoExecute for 300s
```
Also updated tests to cover all possible cases of describing pod with tolerations. See changes in of `TestDescribePodTolerations()` in `describe_test.go`

fix HostAliases' json keys to be hostAlias instead of hostMapping to reflect actual feature name
**What this PR does / why we need it**: a rename was introduce during the middle of #44641 to change from `hostMappings` to `hostAliases`. the Go structs were updated, but I neglected to update the json keys. They should be in sync.
**Special notes for your reviewer**: I messed up. This is an API change. I hope this is still ok to be in the 1.7 release.
**Release note**:
```release-note
HostAliases is now parsed with `hostAliases` json keys to be in line with the feature's name.
```

Revert 44714 manually
#44714 broke backward compatibility for old swagger spec that kubectl still uses. The decision on #47448 was to revert this change but the change was not automatically revertible. Here I semi-manually remove all references to UnixUserID and UnixGroupID and updated generated files accordingly.
Please wait for tests to pass then review that as there may still be tests that are failing.
Fixes#47448
Adding release note just because the original PR has a release note. If possible, we should remove both release notes as they cancel each other.
**Release note**: (removed by caesarxuchao)
UnixUserID and UnixGroupID is reverted back as int64 to keep backward compatibility.

Add E2E tests for Azure internal loadbalancer support, fix an issue for public IP resource deletion.
**What this PR does / why we need it**:
- Add E2E tests for Azure internal loadbalancer support: https://github.com/kubernetes/kubernetes/pull/43510
- Fix an issue that public IP resource not get deleted when switching from external loadbalancer to internal static loadbalancer.
**Special notes for your reviewer**:
1. Add new Azure resource tag to Public IP resources to indicate kubernetes managed resources.
Currently we determine whether the public IP resource should be deleted by looking at LoadBalancerIp property on spec. In the scenario 'Switching from external loadbalancer to internal loadbalancer with static IP', that value might have been updated for internal loadbalancer. So here we're to add an explicit tag for kubernetes managed resources.
2. Merge cleanupPublicIP logic into cleanupLoadBalancer
**Release note**:
NONE

To ensure kubelet doesn't attempt network teardown on HostNetwork
containers that no longer exist but are still checkpointed, make
sure we preserve the HostNetwork property in checkpoints. If
the checkpoint indicates the container was a HostNetwork one,
don't tear down the network since that would fail anyway.

Separate serviceaccount and secret storage config
Fixes#47815, and is required in order to enable the secret encryption feature with a recommended configuration
This passes distinct storage options for serviceaccounts and secrets, since secrets can now have an encrypting transformer associated with them
If unspecified in probe definition, User-Agent will be set to
`kube-probe/<version major.minor>` on httpGet probe types
instead of the default Go User-Agent.

New annotation to add existing Security Groups to ELBs created by AWS cloudprovider
**What this PR does / why we need it**:
When K8S cluster is deployed in existing VPC there might be a need to attach extra SecurityGroups to ELB created by AWS cloudprovider. Example of it can be cases, where such Security Groups are maintained by another team.
**Special notes for your reviewer**:
For tests to pass depends on https://github.com/kubernetes/kubernetes/pull/45168 and therefore includes it
**Release note**:

- Wrapping all node statuses from local storage capacity isolation under an alpha feature check. Currently there should not be any storage statuses.
- Replaced all "storage" statuses with "storage.kubernetes.io/scratch". "storage" should never be exposed as a status.

Serialized protobuf should have stable map order
Leverage `stable_marshaller_all` tag in gogo-protobuf to ensure all of our maps have stable ordering when serialized to protobuf. This preserves the behavior from JSON that we rely on to avoid writing to etcd except when the content has changed.
Will slightly increase allocations (1 slice per non-empty map in an object) during Encode, which has a minor impact on CPU. However, avoiding writes when a client issues a blind put results in significantly less CPU across the whole cluster (avoiding a new etcd version for an Endpoints object might save ~1 core/sec on large clusters).
Fixes#47678
```release-note
The protobuf serialization of API objects has been updated to store maps in a predictable order to ensure that the representation of that object does not change when saved into etcd. This prevents the same object from being seen as being modified, even when no values have changed.
