Tolerate unknown fields in strategic merge patch
When using `apply` or `edit` with an object that has a compiled-in struct, if an unknown server-side field is sent, or is present in a provided file, the strategic merge patch computation fails looking up type info from the go struct
If the field only exists in one side of the patch (is being added or removed), or is identical in both sides of the patch, we should tolerate missing type info, since it doesn't affect the patch.

deprecate and disconnect --output-version
For at least two releases, there haven't been multiple versions of API groups and we don't plan to support conversions in commands other than `kubectl convert`. This disconnects the `--output-version` option to be consistent with conversion agnostic command before it becomes an issue.
@kubernetes/sig-cli-pr-reviews @fabianofranz @smarterclayton
```release-note
`--output-version` is ignored for all commands except `kubectl convert`. This is consistent with the generic nature of `kubectl` CRUD commands and the previous removal of `--api-version`. Specific versions can be specified in the resource field: `resource.version.group`, `jobs.v1.batch`.

[Kubemark] Add option to log hollow-node logs
Ref https://github.com/kubernetes/kubernetes/issues/41613
Added an option to log kubemark hollow-node logs which includes kubelet, kubeproxy and npd logs for each hollow-node.
Setting the env var `ENABLE_HOLLOW_NODE_LOGS=true` should now enable logging for tests.

make: allow overriding quick-release opts
Prior to this change, `make quick-release KUBE_RELEASE_RUN_TESTS=y`
would still not run the tests. This change makes it so such overriding
works.
It also specifies the options as variables, which helps some shells with
tab-completion.
Finally, I plan to add a new "quick-release" option that not everyone will want on in #35249 (`RELEASE_HYPERKUBE_ONLY`), and this sets the needed groundwork to make such an "opt-in for quickness" flag possible.

Update Photon Controller cloud provider for authentication support
Resolve Issue: [#40755](https://github.com/kubernetes/kubernetes/issues/40755)
1. Update the configuration file for Photon Controller cloud provider
2. Only master nodes can communicate with Photon Controller endpoint
3. Enable support for authentication-enabled Photon Controller endpoint
4. Update NodeAddresses function for query from local node
New format of photon controller config file:
```
[Global]
target = https://[LOAD_BALANCER_IP]:443
project = [PROJECT ID]
overrideIP = true
vmID = [LOCAL VM ID]
authentication = true
```
This config file will be automatically created by Photon Controller cluster management.
If authentication file is set to true, then a pc_login_info file should be placed under /etc/kubernetes with username and password.
This file can be created by user directly.
Or the user can choose to use kubernetes secret and a handling pod to avoid directly login to master nodes. This usage will be available with Photon Controller 1.2.
This is a temporary solution before metadata service becomes available in Photon Controller.

Migrate rackspace/gophercloud -> gophercloud/gophercloud
`gophercloud` is the go library we use to interact with openstack. It has recently been renamed and incorporated a number of breaking code cleanups. This change migrates the Kubernetes openstack code (openstack provider, keystone auth, cinder volumes) to the new library.
Fixes#30404
```release-note
The openstack cloud provider config no longer supports the deprecated `api-key` option.
```
Note this PR doesn't change the rackspace provider. It uses some rackspace-specific APIs and continues to use the older rackspace/gophercloud library.

ResourceQuota ability to support default limited resources
Add support for the ability to configure the quota system to identify specific resources that are limited by default. A limited resource means its consumption is denied absent a covering quota. This is in contrast to the current behavior where consumption is unlimited absent a covering quota. Intended use case is to allow operators to restrict consumption of high-cost resources by default.
Example configuration:
**admission-control-config-file.yaml**
```
apiVersion: apiserver.k8s.io/v1alpha1
kind: AdmissionConfiguration
plugins:
- name: "ResourceQuota"
configuration:
apiVersion: resourcequota.admission.k8s.io/v1alpha1
kind: Configuration
limitedResources:
- resource: pods
matchContains:
- pods
- requests.cpu
- resource: persistentvolumeclaims
matchContains:
- .storageclass.storage.k8s.io/requests.storage
```
In the above configuration, if a namespace lacked a quota for any of the following:
* cpu
* any pvc associated with particular storage class
The attempt to consume the resource is denied with a message stating the user has insufficient quota for the matching resources.
```
$ kubectl create -f pvc-gold.yaml
Error from server: error when creating "pvc-gold.yaml": insufficient quota to consume: gold.storageclass.storage.k8s.io/requests.storage
$ kubectl create quota quota --hard=gold.storageclass.storage.k8s.io/requests.storage=10Gi
$ kubectl create -f pvc-gold.yaml
... created

Make controller-manager resilient to stale serviceaccount tokens
Now that the controller manager is spinning up controller loops using service accounts, we need to be more proactive in making sure the clients will actually work.
Future additional work:
* make a controller that reaps invalid service account tokens (c.f. https://github.com/kubernetes/kubernetes/issues/20165)
* allow updating the client held by a controller with a new token while the controller is running (c.f. https://github.com/kubernetes/kubernetes/issues/4672)

Convert HPA controller to support HPA v2 mechanics

The HPA controller continues to make use of the HPA v1 client, but utilizes

Improved code coverage for plugin/pkg/scheduler/algorithm/priorities…
…/most_requested.go
**What this PR does / why we need it**:
Part of #39559 , code coverage improved from 70+% to 80+%
There was a bug in the HPA v1 conversion logic that would occur when
a custom metric and a metric that was encoded in v1 as
targetCPUUtilizationPercentage were used at the same time. In this
case, the custom metric could overwrite the CPU metric, or vice versa.
This fixes that bug, and ensures that the fuzzer tests round-tripping
with multiple metrics.
