syncNetworkUtil in kubelet and fix loadbalancerSourceRange on GCE
fixes: #29997#29039
@yujuhong Can you take a look at the kubelet part?
@girishkalele KUBE-MARK-DROP is the chain for dropping connections. Marked connection will be drop in INPUT/OUTPUT chain of filter table. Let me know if this is good enough for your use case.
Having an A-record and a CNAME-record in the tests led to a confusion
that dns providers support such configurations. This change avoids
that confusion by putting only compatible records for the same domain
name in the tests.

Add NodeName to EndpointAddress object
Adding a new string type `nodeName` to api.EndpointAddress.
We could also do *ObjectReference to the api.Node object instead, which would be more precise for the future.
```
type ObjectReference struct {
Kind string `json:"kind,omitempty"`
Namespace string `json:"namespace,omitempty"`
Name string `json:"name,omitempty"`
UID types.UID `json:"uid,omitempty"`
APIVersion string `json:"apiVersion,omitempty"`
ResourceVersion string `json:"resourceVersion,omitempty"`
// Optional. If referring to a piece of an object instead of an entire object, this string
// should contain information to identify the sub-object. For example, if the object
// reference is to a container within a pod, this would take on a value like:
// "spec.containers{name}" (where "name" refers to the name of the container that triggered
// the event) or if no container name is specified "spec.containers[2]" (container with
// index 2 in this pod). This syntax is chosen only to have some well-defined way of
// referencing a part of an object.
// TODO: this design is not final and this field is subject to change in the future.
FieldPath string `json:"fieldPath,omitempty"`
}

Implement AppArmor Kubelet support
Includes PR https://github.com/kubernetes/kubernetes/pull/29812
Implements the Kubelet logic for AppArmor based on the alpha API proposed [here](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/apparmor.md). Also adds an E2E test, and I ran manual tests.
Remaining work: PodSecurityPolicy support, profile loader daemon, documentation, (maybe) beta API.
/cc @jfrazelle @Amey-D @kubernetes/sig-node
*Note on release-note-none: I am implementing AppArmor over multiple PRs. I will submit a single release note once the implementation is done to cover all of them.*

fix node controller event uid issue
Fix#29289. @smarterclayton ptal. This is not a very elegant fix, if we can use nodeName in log maybe we can set timedValue.Value to node.UID.

Prevent device unmount from deleting dir on failed unmount
This PR cleans up the device unmount code for attachable volumes. Specifically it:
* Prevents deletion of directory via `os.Remove` unless unmount succeeds.
* Moves common shared device unmount logic to a common util file.
