vSphere Cloud Provider: add SAML token authentication support
**What this PR does / why we need it**:
The vSphere cloud provider currently supports username+password based authentication, this PR adds an option to use token based authentication.
**Which issue(s) this PR fixes**:
Fixes#63209
**Special notes for your reviewer**:
For now the config structs and validation are left as-is and
the LoginByToken method is used if the username value is PEM encoded.
In this case of username field configured with the public key, the password
field is expected to be configured with the private key.
In a follow-up PR we can look at collapsing the auth related fields into
a common struct to avoid duplication of field merging and validation.
And then add separate fields for the public and private keys.
**Release note**:
```release-note

Eviction Node e2e test checks for eviction reason
**What this PR does / why we need it**:
Currently, the eviction test simply ensures that pods are marked `Failed`. However, this could occur because of an OOM, rather than an eviction.
To ensure that pods are actually being evicted, check for the Reason in the pod status to ensure it is evicted.

```release-note

Fix formatting for kubelet memcg notification threshold
/kind bug
**What this PR does / why we need it**:
This fixes the following errors (found in [this node_e2e serial test log](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-node-kubelet-serial/4118/artifacts/tmp-node-e2e-49baaf8a-cos-stable-63-10032-71-0/kubelet.log)):
`eviction_manager.go:256] eviction manager attempting to integrate with kernel memcg notification api`
`threshold_notifier_linux.go:70] eviction: setting notification threshold to 4828488Ki`
`eviction_manager.go:272] eviction manager: failed to create hard memory threshold notifier: invalid argument`
**Special notes for your reviewer**:
This needs to be cherrypicked back to 1.10.
This regression was added in https://github.com/kubernetes/kubernetes/pull/60531, because the `quantity` being used was changed from a DecimalSI to BinarySI, which changes how it is printed out in the String() method. To make it more explicit that we want the value, just convert Value() to a string.
**Release note**:
```release-note
Fix memory cgroup notifications, and reduce associated log spam.

Restore pre-1.10 openstack instance naming behavior
As noted in https://github.com/kubernetes/kubernetes/pull/61890#issuecomment-377282182 and https://github.com/kubernetes/kubernetes/issues/62295#issuecomment-389374492, the 1.10 changes to the openstack cloud provider node name computation (in #58502, #61000, and #61890) broke existing deployments that provisioned instances with credentials matching their instance names. It also did not account for version skewed kubelets, which can run 1.8 and 1.9 versions against a 1.10 master, and still register based on instance name.
This PR reverts the incompatible changes to restore pre-1.10 behavior.
Further improvements to handle instances with names that cannot be used as node names are tracked in https://github.com/kubernetes/kubernetes/issues/62295
/assign @dims
/sig openstack
/kind bug
```release-note
Restores the pre-1.10 behavior of the openstack cloud provider which uses the instance name as the Kubernetes Node name. This requires instances be named with RFC-1123 compatible names.

Add memcg notifications for allocatable cgroup
**What this PR does / why we need it**:
Use memory cgroup notifications to trigger the eviction manager when the allocatable eviction threshold is crossed. This allows the eviction manager to respond more quickly when the allocatable cgroup's available memory becomes low. Evictions are preferable to OOMs in the cgroup since the kubelet can enforce its priorities on which pod is killed.
**Which issue(s) this PR fixes**:
Fixes https://github.com/kubernetes/kubernetes/issues/57901
**Special notes for your reviewer**:
This adds the alloctable cgroup from the container manager to the eviction config.

remove decoder from name printing
The extra decoding step inside of name printing isn't useful. It's only current utility is when the content inside of the list is a runtime.Unknown. However, when you're making use of this printer in a CLI, you've read the content in via a builder or a scheme directly. You would logically set this decoder based on that same scheme. If you were unable to decode using the scheme before, you'll simple be unable to do it again here.
Near as I can tell, this would only be useful if objects weren't decoded before printing. There is a unit test that ensures this remains. I'd like to see if any practical tests (cmd, e2e) rely on it.
@smarterclayton @liggitt not many people would have written it to begin with. One of you?
