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!
Fixes#38336

On GCE, node upgrades will now respect PodDisruptionBudgets, if present.

Add some initial resource limits to the ip-masq-agent.
These limits were based on observing the agent over roughly a day RES was typically ~4M for me but I'd like to make sure we have some headroom. If there was a huge config map then this could increase slightly but not significantly since we only allow 64 entries.

Adding a metadata proxy addon
**What this PR does / why we need it**: adds a metadata server proxy daemonset to hide kubelet secrets.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: this partially addresses #8867
**Special notes for your reviewer**:
**Release note**: the gce metadata server can be hidden behind a proxy, hiding the kubelet's token.

Add initializer support to admission and uninitialized filtering to rest storage
Initializers are the opposite of finalizers - they allow API clients to react to object creation and populate fields prior to other clients seeing them.
High level description:
1. Add `metadata.initializers` field to all objects
2. By default, filter objects with > 0 initializers from LIST and WATCH to preserve legacy client behavior (known as partially-initialized objects)
3. Add an admission controller that populates .initializer values per type, and denies mutation of initializers except by certain privilege levels (you must have the `initialize` verb on a resource)
4. Allow partially-initialized objects to be viewed via LIST and WATCH for initializer types
5. When creating objects, the object is "held" by the server until the initializers list is empty
6. Allow some creators to bypass initialization (set initializers to `[]`), or to have the result returned immediately when the object is created.
The code here should be backwards compatible for all clients because they do not see partially initialized objects unless they GET the resource directly. The watch cache makes checking for partially initialized objects cheap. Some reflectors may need to change to ask for partially-initialized objects.
```release-note
Kubernetes resources, when the `Initializers` admission controller is enabled, can be initialized (defaulting or other additive functions) by other agents in the system prior to those resources being visible to other clients. An initialized resource is not visible to clients unless they request (for get, list, or watch) to see uninitialized resources with the `?includeUninitialized=true` query parameter. Once the initializers have completed the resource is then visible. Clients must have the the ability to perform the `initialize` action on a resource in order to modify it prior to initialization being completed.

Set Kubelet Disk Defaults for the 1.7 release
The `--low-diskspace-threshold-mb` flag has been depreciated since 1.6.
This PR sets the default to `0`, and sets defaults for disk eviction based on the values used for our [e2e tests](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/services/kubelet.go#L145).
This also removes the custom defaults for vagrant, as the new defaults should work for it as well.
/assign @derekwaynecarr

```release-note
By default, --low-diskspace-threshold-mb is not set, and --eviction-hard includes "nodefs.available<10%,nodefs.inodesFree<5%"

Support storageclass storage updates to v1

**Special notes for your reviewer**: I had a hard time getting the test to work with how it was handling KUBE_API_VERSIONS and RUNTIME_CONFIG. I would appreciate some extra review attention there. Also, I had to hack in a `cluster-scoped` "namespace" to get the verification portions of the test script to work. I'm definitely open to ideas for how to improve that if needed.
**Release note**:
```release-note
Support updating storageclasses in etcd to storage.k8s.io/v1. You must do this prior to upgrading to 1.8.

appropriate endpoint (Pod) IP for the given resource.
Added code to allow aggregator routing to be optional.
Updated bazel build.
Fixes to cover JLiggit comments.
Added util ResourceLocation method based on Listers.
Fixed issues from verification steps.
Updated to add an interface to obfuscate some of the routing logic.
Collapsed cluster IP resolution in to the aggregator routing
implementation.

Enable the ip-masq-agent on GCE installs
Setting this will trigger cluster/addons/ip-masq-agent/ip-masq-agent.yaml to be installed as an addon, which disable configure IP masquerade for all of RFC1918, rather
than just 10.0/8.
Because the flag defaulted to 10.0/8 we can't just change the default. I think anyone who needs IP masquerade set up should probably use this instead.
@justinsb @kubernetes/sig-cluster-lifecycle-misc
Fixes#11204
@dnardo - any reason not to do this?
Release Note:
```release-note
GCE installs will now avoid IP masquerade for all RFC-1918 IP blocks, rather than just 10.0.0.0/8. This means that clusters can
be created in 192.168.0.0./16 and 172.16.0.0/12 while preserving the container IPs (which would be lost before).
