Add partial CRI container log support.
For https://github.com/kubernetes/kubernetes/issues/44976.
New CRI log format:
```
TIMESTAMP STREAM TAG CONTENT
2016-10-06T00:17:09.669794202Z stdout P log content 1
2016-10-06T00:17:09.669794203Z stdout P log content 2
```
Although unlikely, if in the future we need more metadata in each line, we could extend TAG into multiple tags splitted by `:`.

fixes#53672 ResourceQuota part
**Special notes for your reviewer**:
What I'm concerned most is the change in quota evaluator:
Rather than add check especially for resource hugage, I would prefer add a check list, that could be easily extended by adding corresponding prefix into the list (As far as I know, pluginResources will also support ResourceQuota in later versions)

Updating vsphere cloud provider to support k8s cluster spread across multiple vCenters
**What this PR does / why we need it**:
vSphere cloud provider in Kubernetes 1.8 was designed to work only if all the nodes of the cluster are in one single datacenter folder. This is a hard restriction that makes the cluster not span across different folders/datacenter/vCenters. Users have use-cases to span the cluster across datacenters/vCenters.
**Which issue(s) this PR fixes**
Fixes # https://github.com/vmware/kubernetes/issues/255
**Special notes for your reviewer**:
This is a change purely in vsphere cloud provider and no changes in kubernetes core are needed.
**Release note**:
```release-note
With this change
- User should be able to create k8s cluster which spans across multiple ESXi clusters, datacenters or even vCenters.
- vSphere cloud provider (VCP) uses OS hostname and not vSphere Inventory VM Name.
That means, now VCP can handle cases where user changes VM inventory name.
- VCP can handle cases where VM migrates to other ESXi cluster or datacenter or vCenter.
The only requirement is the shared storage. VCP needs shared storage on all Node VMs.
```
Internally tested and reviewed the code.

Device plugin API merge of handler and manager
**What this PR does / why we need it**: We are trying different approaches to make the device plugin implementation simpler and more robust. One option is to merge the notion of the `device_plugin_handler` into the `device_manager`. This is for several reasons:
1) Some calls go directly from handler to manager, adding little value.
2) The separation of concern is not clear between the two components. They have a 1:1 relationship.
3) The separation and abstractions needed are at a different level. Code that can be refactored will most likely live in abstractions which hide details around lock acquisition and check pointing.
In this PR, we will **just** merge the two interfaces. After this, there is several opportunities for simplifying and cleaning up the device plugin.
Fixes#55180
**Special notes for your reviewer**: This is a WIP. May very well get dropped, but keeping up for the sake of early sharing and showing the progress of the code move.
**Release note**:

seccomp is an alpha feature and not feature gated
Move SeccompProfileRoot to KubeletFlags and document flag as alpha.
wrt https://github.com/kubernetes/kubernetes/pull/53833#issuecomment-345396575, seccomp is an alpha feature, but this isn't clearly documented anywhere (the annotation just has the word "alpha" in it, and that's your signal that it's alpha).
Since seccomp was around before feature gates, it doesn't have one.
Thus SeccompProfileRoot should not be part of KubeletConfiguration, and this PR moves it to KubeletFlags, and amends the help text to note the alpha state of the feature.

deviceplugin: fix race when multiple plugins are registered
**What this PR does / why we need it**:
When registering multiple device plugins to Kubelet concurrently, there exists a race that crashes the Kubelet.
Consider two plugins: D1 and D2. The call order method is roughly
D1 -> manager.go:register -> endpoint.go:listAndWatch -> device_plugin_handler.go:(*D1).callback
D2 -> manager.go:register -> endpoint.go:listAndWatch -> device_plugin_handler.go:(*D2).callback
The callback function accesses HandlerImpl's allDevices map that maps (resourceName -> DeviceID). If both plugins reach these accesses at the same time, Kubelet crashes with "fatal error: concurrent map read and map write".
This can be solved by making sure handler is locked when allDevices are being updated. The functionality is needed to avoid Kubelet crashes when multiple device plugins are trying to register with Kubelet at the same moment. Occurs frequently when single binary tries to register itself as multiple plugins.

Stop using VersionedObject in resource.Builder, use unstructured
Remove the need for kubectl callers to distinguish between unstructured and versioned / type aware builders. The factory should create a single builder than can be set to return unstructured objects. Callers can then use one of the new helpers on `resource.Info` to convert the objects into the desired form - `Internal()` for printers, `Typed()` for external versions, and `Unstructured()` to ensure the object is in the right state. Leverages the new scheme support for unstructured conversion so that higher level callers can perform best effort conversion (get typed versions if you have them, otherwise use default behavior).
`get.go` demonstrates this by removing the previous logic that depended on the underlying scheme. Other commands are updated to be consistent.
Includes #55650 and #55647.

Refactor `reconcileAutoscaler` method in hpa
**What this PR does / why we need it**:
There have been a couple of recent bugs in the "normalizing" part of the
`reconcileAutoscaler` method. This part of the code base is responsible
for, among other things, taking the suggested desired replicas based on
the metrics, ensuring it conforms to certain conditions, and updating it
if it does not. Isolate the part that converts the desired replicas
based on a given set of rules into its own function.
We are refactoring this part of the code base to make the logic simpler
and to make it easier to write unit tests.
