auth: allow nodes to create tokens for svcaccts of pods

ref https://github.com/kubernetes/kubernetes/issues/58790

running on them. nodes essentially have the power to do this today
but not explicitly. this allows agents using the node identity to
take actions on behalf of local pods.

```release-note
The node authorizer now allows nodes to request service account tokens for the service accounts of pods running on them.

Add Garbage Collector e2e conformance tests

**What this PR does / why we need it**:
The garbage collector is a core component of kubernetes and needs to be tested by conformance, so its functionality can be relied on in any kubernetes environment.

As we can see in [testgrid](https://k8s-testgrid.appspot.com/sig-api-machinery#gce), the garbage collector tests being promoted by this PR are consistently passing. And the intention to promote them to conformance tests was laid out by [this document](https://docs.google.com/document/d/1h2S9ff9N-4MKqfayE3A8TqjD_qIwuND_dAhOAJFxYS0)

**Special notes for your reviewer**:
The last two tests in this file are not added as conformance tests because they involve beta features (custom resources and cronjobs), and conformance tests are only allowed for features in GA.

**Release note**:
```release-note
New conformance tests added for the Garbage Collector
```

[e2e ingress-gce] Enhance cleanup logic for pre-shared-cert test

**What this PR does / why we need it**:
Pre-shared-cert test are flaky (https://k8s-testgrid.appspot.com/sig-network-gce#ingress-gce-e2e&width=5), mostly due to the orphaned ssl cert.

This PR enhances the cleanup logic to continue deleting the orphaned cert for this case (without this test will panic on TryDeleteIngress if no ingress is created).

Reduce number of pods created for local PV stress test

**What this PR does / why we need it**:
Local PV stress test is flaking.  Failed runs show that test is timing out at 47/50 pods.  Reduce the number of pods created by the test so that it's not so close to the max timeout.

**Special notes for your reviewer**:

Conformance: Add StatefulSet tests.

Mark StatefulSet tests as Conformance where possible. I've excluded those that depend on a dynamic provisioner and a default storage class (i.e. those that use PVC), because I don't think those things are required for Conformance at this time.

Move retry-based updates to a different pkg

Ref https://github.com/kubernetes/kubernetes/issues/55860

This PR is not really changing retries for updates (it was there even before), just moving it to a separate place where we can add more functions later.
I'll work on my earlier PR https://github.com/kubernetes/kubernetes/pull/56075 to make RC Scale() poll-based to solve issues like https://github.com/kubernetes/kubernetes/issues/56064.

Made a couple API changes to deviceplugin/v1beta1 to avoid future

incompatible API changes:
- Add GetDevicePluginOptions rpc call. This is needed when we switch
  from Registration service to probe-based plugin watcher.
- Change AllocateRequest and AllocateResponse to allow device requests
  from multiple containers in a pod. Currently only made mechanical
  change on the devicemanager and test code to cope with the API but
  still issues an Allocate call per container. We can modify the
  devicemanager in 1.11 to issue a single Allocate call per pod.
  The change will also facilitate incremental API change to communicate
  pod level information through Allocate rpc if there is such future
  need.

expunge the word 'manifest' from Kubelet's config API

The word 'manifest' technically refers to a container-group specification
that predated the Pod abstraction. We should avoid using this legacy
terminology where possible. Fortunately, the Kubelet's config API will
be beta in 1.10 for the first time, so we still had the chance to make
this change.

I left the flags alone, since they're deprecated anyway.

I changed a few var names in files I touched too, but this PR is the
just the first shot, not the whole campaign
(`git grep -i manifest | wc -l -> 1248`).

```release-note
Some field names in the Kubelet's now v1beta1 config API differ from the v1alpha1 API: PodManifestPath is renamed to PodPath, ManifestURL is renamed to PodURL, ManifestURLHeader is renamed to PodURLHeader.
