Made WaitForReplicas and EnsureDesiredReplicas use PollImmediate and improved logging.
**What this PR does / why we need it**: Most importantly, this results in better logging: timeout is logged at the level of the caller, not the helper function, helping debugging.

Use actual hostname when creating network e2e test pod
**What this PR does / why we need it**:
This changes a e2e framework network test Pod use the actual hostname value to match the `kubernetes.io/hostname` label in it's `NodeSelector`. Currently it assumes the Node name will match that hostname label which is not true in all environments.

implements StatefulSet update
**What this PR does / why we need it**:
1. Implements rolling update for StatefulSets
2. Implements controller history for StatefulSets.
3. Makes StatefulSet status reporting consistent with DaemonSet and ReplicaSet.
https://github.com/kubernetes/features/issues/188
**Special notes for your reviewer**:
**Release note**:
```release-note
Implements rolling update for StatefulSets. Updates can be performed using the RollingUpdate, Paritioned, or OnDelete strategies. OnDelete implements the manual behavior from 1.6. status now tracks
replicas, readyReplicas, currentReplicas, and updatedReplicas. The semantics of replicas is now consistent with DaemonSet and ReplicaSet, and readyReplicas has the semantics that replicas did prior to this release.

Don't parse human-readable output from gcloud in tests
This is the reason `[k8s.io] Services should be able to change the type and ports of a service [Slow]` is currently failing on GKE e2e tests. For GKE jobs we run a prerelease version of gcloud, in which the default command output was changed.
gcloud's default output for commands is human readable, and is subject to change. Anything scripting against gcloud should always pass `--format=json|yaml|value(...)` so you get standardized output.

Implements history utilities for ControllerRevision in the controller/history package
StatefulSetStatus now has additional fields for consistency with DaemonSet and Deployment
StatefulSetStatus.Replicas now represents the current number of createdPods and StatefulSetStatus.ReadyReplicas is the current number of ready Pods

Multizone static pv test
**What this PR does / why we need it**:
Adds an e2e test for checking that pods get scheduled to the same zone as statically created PVs. This tests the PersistentVolumeLabel admission controller, which adds zone and region labels when PVs are created. As part of this, I also had to make changes to volume test utility code to pass in a zone parameter for creating PDs, and also had to add an argument to the e2e test program to accept a list of zones.
Fixes#46995

Respect PDBs during node upgrades and add test coverage to the ServiceTest upgrade test.
This is still a WIP... needs to be squashed at least, and I don't think it's currently passing until I increase the scale of the RC, but please have a look at the general outline. Thanks!

Local storage plugin
**What this PR does / why we need it**:
Volume plugin implementation for local persistent volumes. Scheduler predicate will direct already-bound PVCs to the node that the local PV is at. PVC binding still happens independently.

Alpha feature: Local volume plugin allows local directories to be created and consumed as a Persistent Volume. These volumes have node affinity and pods will only be scheduled to the node that the volume is at.

Support grabbing test suite metrics
**What this PR does / why we need it**:
Add support for grabbing metrics that cover the entire test suite's execution.
Update the "interesting" controller-manager metrics to match the
current names for the garbage collector, and add namespace controller
metrics to the list.
If you enable `--gather-suite-metrics-at-teardown`, the metrics file is written to a file with a name such as `MetricsForE2ESuite_2017-05-25T20:25:57Z.json` in the `--report-dir`. If you don't specify `--report-dir`, the metrics are written to the test log output.
I'd like to enable this for some of the `pull-*` CI jobs, which will require a separate PR to test-infra.

GCE - Refactor API for firewall and backend service creation
**What this PR does / why we need it**:
- Currently, firewall creation function actually instantiates the firewall object; this is inconsistent with the rest of GCE api calls. The API normally gets passed in an existing object.
- Necessary information for firewall creation, (`computeHostTags`,`nodeTags`,`networkURL`,`subnetworkURL`,`region`) were private to within the package. These now have public getters.
- Consumers might need to know whether the cluster is running on a cross-project network. A new `OnXPN` func will make that information available.
- Backend services for regions have been added. Global ones have been renamed to specify global.
- NamedPort management of instance groups has been changed from an `AddPortsToInstanceGroup` func (and missing complementary `Remove...`) to a single, simple `SetNamedPortsOfInstanceGroup`
- Addressed nitpick review comments of #45524
ILB needs the regional backend services and firewall refactor. The ingress controller needs the new `OnXPN` func to decide whether to create a firewall.

Apply KubeProxyEndpointLagTimeout to ESIPP tests
Fixes#46533.
The previous construction of ESIPP tests is weird, so I redo it a bit.
A 30 seconds `KubeProxyEndpointLagTimeout` is introduced, as these tests ain't verifying performance, may be better to not make it too tight.

Make GCE load-balancers create health checks for nodes
From #14661. Proposal on kubernetes/community#552. Fixes#46313.
Bullet points:
- Create nodes health check and firewall (for health checking) for non-OnlyLocal service.
- Create local traffic health check and firewall (for health checking) for OnlyLocal service.
- Version skew:
- Don't create nodes health check if any nodes has version < 1.7.0.
- Don't backfill nodes health check on existing LBs unless users explicitly trigger it.
**Release note**:
```release-note
GCE Cloud Provider: New created LoadBalancer type Service now have health checks for nodes by default.
An existing LoadBalancer will have health check attached to it when:
- Change Service.Spec.Type from LoadBalancer to others and flip it back.
- Any effective change on Service.Spec.ExternalTrafficPolicy.

Support parallel scaling on StatefulSets
Fixes#41255
```release-note
StatefulSets now include an alpha scaling feature accessible by setting the `spec.podManagementPolicy` field to `Parallel`. The controller will not wait for pods to be ready before adding the other pods, and will replace deleted pods as needed. Since parallel scaling creates pods out of order, you cannot depend on predictable membership changes within your set.
