This will create the necessary certificates.
On GCE is will upload those certificates to Metadata.
They are then pulled down on to the kube-apiserver.
They are written to the /etc/src/kubernetes/pki directory.
Finally they are loaded vi the appropriate command line flags.
The requestheader-client-ca-file can be seen by running the following:-
kubectl get ConfigMap extension-apiserver-authentication
--namespace=kube-system -o yaml
Minor bug fixes.
Made sure AGGR_MASTER_NAME is set up in all configs.
Clean up variable names.
Added additional requestheader configuration parameters.
Added check so that if there is no Aggregator CA contents we won't start
the aggregator with the relevant flags.

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.

Configure NPD version through env variable
This lets user specify NPD version to be installed with kubernetes.
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.

Create a subnet for reserving the service cluster IP range
This will be done if IP aliases is enabled on GCP.
```release-note
NONE
```
Packaged the script as a docker container stored in gcr.io/google-containers
A daemonset deployment is included to make it easy to consume the installer
A cluster e2e has been added to test the installation daemonset along with verifying installation
by using a sample CUDA application.
Node e2e for GPUs updated to avoid running on nodes without GPU devices.

Update Calico add-on
**What this PR does / why we need it:**
Updates Calico to the latest version using self-hosted install as a DaemonSet, removes Calico's dependency on etcd.
- [x] Remove [last bits of Calico salt](175fe62720/cluster/saltbase/salt/calico/master.sls (L3))
- [x] Failing on the master since no kube-proxy to access API.
- [x] Fix outgoing NAT
- [x] Tweak to work on both debian / GCI (not just GCI)
- [x] Add the portmap plugin for host port support
Maybe:
- [ ] Add integration test

GCE will properly regenerate basic_auth.csv on kube-apiserver start.
**What this PR does / why we need it**:
If basic_auth.csv does not exist we will generate it as normal.
If basic_auth.csv exists we will remove the old admin password before adding the "new" one. (Turns in to a no-op if the password exists).
This did not work properly before because we were replacing by key, where the key was the password. New password would not match and so not replace the old password.

Added a METADATA_CLOBBERS_CONFIG flag
METADATA_CLOBBERS_CONFIG controls if we consider the values on disk or in
metadata to be the canonical source of truth. Currently defaulting to
false for GCE and forcing to true for GKE.
Added handling for older forms of the basic_auth.csv file.
Fixed comment to reflect new METADATA_CLOBBERS_CONFIG var.
