Increase api latency threshold for cluster-scoped list calls

Recent change from @smarterclayton (https://github.com/kubernetes/kubernetes/pull/52237) added scope to apiserver metrics. As a result, our current threshold for list calls is no longer sufficient for all-namespace calls which are now being measured separately from namespaced lists. For e.g (from our [last 5k run](https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gce-scale-performance/37)):

```
WARNING Top latency metric: {Resource:pods Subresource: Verb:LIST Scope:cluster Latency:{Perc50:4.498374s Perc90:7.548079s Perc99:8.169389s Perc100:0s} Count:1400}

update-staging-godeps: only mangle staging repos in staging Godeps.json

- this re-adds non-staging k8s.io/* repos to the staging Godeps.jsons
- x-outs instead of removing of staging dependencies in order to get a
  precise trigger for a complete godep restore+save run in the publisher
  bot.

The first breaks k8s.io/kube-aggregator's staging export.

The second potentially leads to inconsistent godeps in our exported staging repos.

Support kubernetes-anywhere provider

**What this PR does / why we need it**:

Implements a new `kubernetes-anywhere` provider to allow upgrade testing in the e2e binary. This is the final step to allow https://github.com/kubernetes/test-infra/pull/4495 and https://github.com/kubernetes/kubernetes-anywhere/pull/450.

**Which issue this PR fixes**:

https://github.com/kubernetes/kubeadm/issues/311

**Special notes for your reviewer**:

Some questions I had

- Does the `--provider` flag specified [here](https://github.com/jamiehannaford/test-infra/blob/dbbf6261e0b44fc81944ed5c3b7152005cc0f1ff/jobs/config.json#L8587) get sent to the flag defined [here](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/test_context.go#L219)? Or should I add another `--provider` flag inside `--upgrade_args` like this: `--upgrade_args=... --provider=kubernetes-anywhere`?
- Is it necessary to add waiting logic after the `make` command, or will it implicitly handle that by itself?

Some other points:

- I chose `sed` to manipulate the current kubernetes-anywhere `.config` rather than duplicating another [`anywhere.go`](https://github.com/kubernetes/test-infra/blob/master/kubetest/anywhere.go). One suggestion was to use `jq` but since the config on disk is not serialized to JSON yet, I'm not sure how that'd work.
- Since I don't have a GCE/GKE account or vCenter, I can't actually verify the e2e binary works. I've managed to build it, but if somebody could quickly run a smoke test, I'd appreciate it. This is my first poke around test-infra and e2e, so there might be some plumbing missing

Kubelet weird output fix

**What this PR does / why we need it**:
All kube binaries print the following message at the top when executed:
```
2017/08/28 21:37:12 proto: duplicate proto type registered: google.protobuf.Any
2017/08/28 21:37:12 proto: duplicate proto type registered: google.protobuf.Duration
2017/08/28 21:37:12 proto: duplicate proto type registered: google.protobuf.Timestamp
```
This PR addresses the above issue
It involves the following two changes:
1. Updating vendor packages
- Removes everything under the repo ``go.pedge.io``
- Updates repo libopenstorage/openstorage (which was using the above package)
2. Updates the portworx volume native driver to adhere to the newly vendor'ed code.

FC plugin: Return target wwn + lun at GetVolumeName()

**What this PR does / why we need it**:

At volume attach/detach controller, GetVolumeName() is
expected to return unique volume identifier, but FC
plugin didn't return unique identifier if user specified
FC volume using target wwn and lun.

In order to return unique identifier, GetVolumeName()
should use combination of target wwn and lun.

**Which issue this PR fixes** : fixes #52690

**Special notes for your reviewer**:

Should we use same format of unique volume identifier between v1.7 and v1.8 `for the purpose of backward compatibility?`

- At v1.7(before introducing attach/detach function), unique ID was pod's uuid + volume name
