Expand the use of "1M" to the corresponding number of bytes, since
support for size suffix was only added to `ipcmk` in util-linux 2.27
which is not yet available in some Linux distributions.
Tested by running `make test-e2e-node` against distributions with ipcmk
that supports and doesn't support the suffix syntax, all of them passed.

Fix kubectl explain for cronjobs
**What this PR does / why we need it**:
`kubectl explain cronjob` was failing with `error: Couldn't find resource for "batch/v1, Kind=CronJob"` the reason for that is that even though we were getting the group and version from the mapper, we always rewrote it with the default value for a specific group, unless user specified the output version.
**Special notes for your reviewer**:
**Release note**:
```release-note
Fix kubectl explain for resources not existing in default version of API group

Add list of pods that use a volume to multiattach events
So users knows what pods are blocking a volume and can realize their error.
**Release note**:
```release-note
NONE
```
UX:
* User can get one of following events, depending what other pod(s) are already using a volume and in which namespace they are:
```
Multi-Attach error for volume"volume-name" Volume is already exclusively attached to one node and can't be attached to another
Multi-Attach error for volume "volume-name" Volume is already used by pod(s) pod3 and 1 pod(s) in different namespaces
```
* controller-manager gets always full logs:
* When the node where is the volume attached is known:
```
Multi-Attach error for volume "volume-name" (UniqueName: "fake-plugin/volume-name") from node "node1" Volume is already used by pods ns2/pod2, ns1/pod3 on node node2, node3
```
* When the node where is the volume attached is not known:
```
Multi-Attach error for volume "volume-name" (UniqueName: "fake-plugin/volume-name") from node "node1" Volume is already exclusively attached to node node2 and can't be attached to another
```

Fix equivalence cache invalidation of Node condition.
Equivalence cache for CheckNodeConditionPred becomes invalid when

Node.Status.Conditions does not change, so move the logic around.
This logic is covered by integration test

Rename package deviceplugin => devicemanager.
**What this PR does / why we need it**:
Fixes#58795
/kind cleanup
Rename package `deviceplugin` to `devicemanager` for consistency.
We already have components named Container manager and CPU manager. The device plugin package similarly contains an interface called `Manager`. The fact that the manager has plugins is somewhat incidental to the purpose of the package itself.
Note that this rename only affects internal API. The external gRPC interface still exports a package called deviceplugin.

Never let cluster-scoped resources skip webhooks
Fix#57964
This allows user write webhooks for cluster-scoped custom resources.
We still need to figure out how to selectively exempt cluster-scoped resources from webhooks to avoid bootstrapping deadlocks. For now, if a deadlock occurs, users can work around by first deleting the webhook configuration, then rebooting the webhook, then re-enabling the webhook configuration.
```release-note
Bug fix: webhooks now do not skip cluster-scoped resources
Action required: Before upgrading your Kubernetes clusters, double check if you had configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), these webhooks will start to take effect. Delete/modify the configs if that's not desirable.

[GCE cloud provider] Ensure hosts are updated in EnsureLoadBalancer()
**What this PR does / why we need it**:
From https://github.com/kubernetes/kubernetes/issues/56527, the `EnsureLoadBalancer()` implementation in GCE external LB doesn't always update the hosts (nodes). This PR makes it to do so.
Previously, the only situation where `ensureExternalLoadBalancer()` will not update hosts is when hosts are updated but there is no other changes that trigger target pool update (for which we delete&recreate target pool and hence updates the hosts). So the main change here is detecting that condition and call `updateTargetPool()`.

PSP: improve parsing and validation of SELinux levels
**What this PR does / why we need it**:
At this moment, when we're comparing SELinux levels of PSP and container, we compare them as strings. We don't take into account that categories in a level may be specified in a different order (for example, `s0:c0,c6` is the same as `s0:c6,c0`).
This PR improves handling of SELinux levels by doing logical comparison.

By default block service proxy to external IP addresses.
**What this PR does / why we need it**:
Currently, the Service Proxy on the APIServer allows unrestricted access to any IP address that the APIServer machine can reach. This is likely undesirable in many cases.
Update the service proxy so that it filters Endpoints to only those that have a TargetRef that matches a known Pod.

Fix master regex when running multiple clusters
**What this PR does / why we need it**:
I'm running two Kubernetes clusters on GCE. One for production and one for staging. The instance prefix I use for production is `kubernetes` and for staging it's `staging-kubernetes`. This caused a problem when running `kube-up.sh` for production because when it tries to find all instances which match `kubernetes(-...)?` it finds both the production and staging instances. This probably results in multiple problems, but the most noticeable one for me was that `INITIAL_ETCD_CLUSTER` was incorrect and so etcd wouldn't start up correctly so the api server doesn't start up correctly so nothing else starts up. I tested this manually and it seems to work for me, but I didn't write an automated test.
