If a user attempts to use basic auth, and the username/password combination
is rejected, the authenticator should return an error. This distinguishes
requests that did not provide username/passwrod (and are unauthenticated
without error) from ones that attempted to, and failed.

Log that debug handlers have been turned on.
**What this PR does / why we need it**: PR allows user to have a message in logs that debug handlers are on. It should allow the operator to know and automate a check for the case where debug has been left on.
**Release note**:
```
NONE
```
Conversions can mutate the underlying object (and ours were).
Make a deepcopy before our first conversion at the very start
of the reconciler method in order to avoid mutating the shared
informer cache during conversion.

changes to cleanup the volume plugin for recycle
**What this PR does / why we need it**:
Code cleanup. Changing from creating a new interface from the plugin, that then calls a function to recycle a volume, to adding the function to the plugin itself.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#26230
**Special notes for your reviewer**:
Took same approach from closed PR #28432.
Do you want the approach to be the same for NewDeleter(), NewMounter(), NewUnMounter() and should they be in this same PR or submit different PR's for those?
**Release note**:
```NONE

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`.

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.

add InternalDNS/ExternalDNS node address types
This PR adds internal/external DNS names to the types of NodeAddresses that can be reported by the kubelet.
will spawn follow up issues for cloud provider owners to include these when possible
```release-note
Nodes can now report two additional address types in their status: InternalDNS and ExternalDNS. The apiserver can use `--kubelet-preferred-address-types` to give priority to the type of address it uses to reach nodes.

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.

Use watch param instead of deprecated /watch/ prefix
Switches clients to use watch param instead of /watch/ prefix
```release-note
Clients now use the `?watch=true` parameter to make watch API calls, instead of the `/watch/` path prefix
```
