allow etcd2/3 choice when bringing up a local cluster, default to etcd3
**What this PR does / why we need it**: local-up-cluster currently doesn't allow you to select which etcd version to use, here we allow you to select one, since k8s is moving towards etcd3 we suggest it to be the default.
**Special notes for your reviewer**: Note, i didnt realize this until i had used https://github.com/kubernetes/kubernetes/pull/42656 which made it immediately clear.

add singular resource names to discovery
Adds the singular resource name to our resource for discovery. This is something we've discussed to remove our pseudo-pluralization library which is unreliable even for english and really has no hope of properly handling other languages or variations we can expect from TPRs and aggregated API servers.
This pull simply adds the information to discovery, it doesn't not re-wire any RESTMappers.

```release-note
API resource discovery now includes the `singularName` used to refer to the resource.

add local option to APIService
APIServices need an option to avoid proxying in cases where the groupversion is handled later in the chain. This will allow a coherent and complete set of APIServices, but won't require extra connections.

Cleanup make test-integration
``make test-integration`` was using the first positional arg passed to ``WHAT`` to filter the list of integration test packages. This PR switches to passing ``WHAT`` verbatim to be consistent with how ``make test`` works. That means the new way to scope execution to a single integration package will be:
```bash
make test-integration WHAT="./test/integration/auth" KUBE_TEST_ARGS="-run=^TestKindAuthorization$"
```
Instead of:
```bash
make test-integration WHAT="auth -test.run=^TestKindAuthorization$"
```
This PR also ensures that the script exits after running a single test case and that etcd cleanup is not done twice at the end of a successful test run. Both were issues encountered while diagnosing the scoping issue.

Update hack scripts to use godep v79 and ensure_godep_version
**What this PR does / why we need it**:
Based on #42965 and https://github.com/kubernetes/kubernetes/pull/42958#discussion_r105568318, this pins the godep version at v79, which should fix some issues when running godep in go1.8 local environments.

**Special notes for your reviewer**:
This should likely get the v1.6 milestone so that it can be merged into master. While I'm setting a default godep version, I'm continuing to use the local pins per this comment: https://github.com/kubernetes/kubernetes/pull/42965#issuecomment-285962723 .

[Bug] Handle container restarts and avoid using runtime pod cache while allocating GPUs
Fixes#42412
**Background**
Support for multiple GPUs is an experimental feature in v1.6.
Container restarts were handled incorrectly which resulted in stranding of GPUs
Kubelet is incorrectly using runtime cache to track running pods which can result in race conditions (as it did in other parts of kubelet). This can result in same GPU being assigned to multiple pods.
**What does this PR do**
This PR tracks assignment of GPUs to containers and returns pre-allocated GPUs instead of (incorrectly) allocating new GPUs.
GPU manager is updated to consume a list of active pods derived from apiserver cache instead of runtime cache.
Node e2e has been extended to validate this failure scenario.
**Risk**
Minimal/None since support for GPUs is an experimental feature that is turned off by default. The code is also isolated to GPU manager in kubelet.
**Workarounds**
In the absence of this PR, users can mitigate the original issue by setting `RestartPolicyNever` in their pods.
There is no workaround for the race condition caused by using the runtime cache though.
Hence it is worth including this fix in v1.6.0.

Fix deployment generator after introducing deployments in apps/v1beta1
This PR does two things:
1. Switches all generator to produce versioned objects, to bypass the problem of having an object in multiple versions, which then results in not having stable generator (iow. producing exactly the same object).
2. Introduces new generator for `apps/v1beta1` deployments.
