Make ThirdPartyResource a root scoped object
ThirdPartyResource (the registration of a third party type) belongs at the cluster scope. It results in resource handlers installed in every namespace, and the same name in two namespaces collides (namespace is ignored when determining group/kind).
ThirdPartyResourceData (an actual instance of that type) is still namespace-scoped.
This PR moves ThirdPartyResource to be a root scope object. Someone previously using ThirdPartyResource definitions in alpha should be able to move them from namespace to root scope like this:
setup (run on 1.2):
```
kubectl create ns ns1
echo '{"kind":"ThirdPartyResource","apiVersion":"extensions/v1beta1","metadata":{"name":"foo.example.com"},"versions":[{"name":"v8"}]}' | kubectl create -f - --namespace=ns1
echo '{"kind":"Foo","apiVersion":"example.com/v8","metadata":{"name":"MyFoo"},"testkey":"testvalue"}' | kubectl create -f - --namespace=ns1
```
export:
```
kubectl get thirdpartyresource --all-namespaces -o yaml > tprs.yaml
```
remove namespaced kind registrations (this shouldn't remove the data of that type, which is another possible issue):
```
kubectl delete -f tprs.yaml
```
... upgrade ...
re-register the custom types at the root scope:
```
kubectl create -f tprs.yaml
```
Additionally, pre-1.3 clients that expect to read/write ThirdPartyResource at a namespace scope will not be compatible with 1.3+ servers, and 1.3+ clients that expect to read/write ThirdPartyResource at a root scope will not be compatible with pre-1.3 servers.

Having internal and external integer types being different hides
potential conversion problems. Propagate that out further (which will
also allow us to better optimize conversion).

Make all defaulters public
Will allow for generating direct accessors in conversion code instead of using reflection.

Add kubelet flags for eviction threshold configuration
This PR just adds the flags for kubelet eviction and the associated generated code.
I am happy to tweak text, but we can also do that later at this point in the release.
Since this causes codegen, I wanted to stage this first.

rkt: bump rkt version to 1.2.1
Upon bumping the rkt version, `--hostname` is supported. Also we now gets the configs from the rkt api service, so `stage1-image` is deprecated.
