update github.com/matttproud/golang_protobuf_extensions to 1.0.1
**What this PR does / why we need it**:
This updates github.com/matttproud/golang_protobuf_extensions to a released
version.
There's no significant change in the code itself, and the corresponding
tests (which are not vendored) behave better with vgo (see details in #65683).

Just after creating a PV, its phase is "Pending" and its finalizers
doesn't contain "kubernetes.io/pv-protection". If the e2e test performs
so faster than the target k8s cluster, the test fails because the PV is
not ready. This adds WaitForPersistentVolumePhase() for waiting the
phase "Available" to avoid such situation.

should check all error in ResourceCollector.Start()
Signed-off-by: yanxuean <yan.xuean@zte.com.cn>
**What this PR does / why we need it**:
1. We should check both errors.
test/e2e_node/resource_collector.go
```
func (r *ResourceCollector) Start() {
// Get the cgroup container names for kubelet and runtime
kubeletContainer, err := getContainerNameForProcess(kubeletProcessName, "")
runtimeContainer, err := getContainerNameForProcess(framework.TestContext.ContainerRuntimeProcessName, framework.TestContext.ContainerRuntimePidFile)
if err == nil {
systemContainers = map[string]string{
stats.SystemContainerKubelet: kubeletContainer,
stats.SystemContainerRuntime: runtimeContainer,
}
}
```
2. redundant compare
The Timestamp.Equal is unlikely to occur, because we have met Timestamp.Before.
```
if oldStats, ok := oldStatsMap[name]; ok && oldStats.Timestamp.Before(newStats.Timestamp) {
if oldStats.Timestamp.Equal(newStats.Timestamp) {
continue
}
r.buffers[name] = append(r.buffers[name], computeContainerResourceUsage(name, oldStats, newStats))
}

apiserver: pass the parent request context when creating InputStream
**What this PR does / why we need it**:
This ensures that request cancellation will be propagated properly to
the client used to create the stream. Without this fix, the apiserver
and the kubelet may leak resources (e.g., goroutine, inotify watches).
One such example is that if user run `kubectl logs -f <container that
don't produce new logs)` and then enter ctrl-c, both kubelet and
apiserver will hold on to the connection and resources indefinitely.

Synchronous & unbatched audit log writes
**What this PR does / why we need it**:
When enabling buffered audit log file writes to reduce latency under high load, we shouldn't be batching the writes, as the large data write can have an inverse (though unpredictable) impact. Additionally, batched audit log writes should not be done asynchronously, as this just creates lock contention on the log writer.

dockershim/network: pass ipRange CNI capabilities
**What this PR does / why we need it**:
Updates the dynamic (capability args) passed from Kubernetes to the CNI plugin. This means CNI plugin authors can offer more features and / or reduce their dependency on the APIServer.
Currently, we only pass the `portMappings` capability. CNI now supports `bandwidth` for bandwidth limiting and `ipRanges` for preferred IP blocks. This PR adds support for these two new capabilities.
Bandwidth limits are provided - as implemented in kubenet - via the pod annotations `kubernetes.io/ingress-bandwidth` and `kubernetes.io/egress-bandwidth`.
The ipRanges field simply passes the PodCIDR. This does mean that we need to change the NodeReady algorithm. Previously, we would only set NodeNotReady on missing PodCIDR when using Kubenet. Now, if the CNI configuration includes the `ipRanges` capability, we need to do the same.
**Which issue(s) this PR fixes**:
Fixes#64393
**Release note**:
```release-note
The dockershim now sets the "bandwidth" and "ipRanges" CNI capabilities (dynamic parameters). Plugin authors and administrators can now take advantage of this by updating their CNI configuration file. For more information, see the [CNI docs](https://github.com/containernetworking/cni/blob/master/CONVENTIONS.md#dynamic-plugin-specific-fields-capabilities--runtime-configuration)

**What this PR does / why we need it**:

**Release note**:
```release-note
Expose `/debug/flags/v` to allow kubelet dynamically set glog logging level. If want to change glog level to 3, you only have to send a PUT request like `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`.

Avoid unnecessary DaemonSet collisionCount bump
**What this PR does / why we need it**: Sometimes DaemonSet controller will bump its collisionCount more than necessary when the collisionCount of the DaemonSet in the cache store hasn't been updated. This won't affect users, as collisionCount is only used for creating unique hash and the number doesn't matter as long as it changes. This fix avoids the unnecessary collisionCount updates and de-flakes the DaemonSet test for collisionCount.

If PV is bound by external PV binder (e.g. kube-scheduler), it's
possible on heavy load that corresponding PVC is not synced to
controller local cache yet.
