This drops another dependency on k8s.io/kubernetes.
This does have the unfortunate side effect that implementers will now
get a compile error until they update their code to use the new type.
Just as a note:
The stats types have moved to k8s.io/kubelet, however the stats types
are only there as of v1.20.
Currently we support older versions than v1.20, and even our go.mod
imports from v1.19.
For now we copy the types in. Later we can remove the type defs and
change them to type aliases to the k8s.io/kubelet types (which prevents
another compile time issue).
Anything relying on type assertions to determine if something implements
this method will, unfortunately, be broken and it will be hard to notice
until runtime. We need to make sure to call this out in the release
notes.

* Move tracing exporter registration
This doesn't belong in the library and should be configured by the
consumer of the opencensus package.
* Rename `vkublet` package to `node`
`vkubelet` does not convey any information to the consumers of the
package.
Really it would be nice to move this package to the root of the repo,
but then you wind up with... interesting... import semantics due to the
repo name... and after thinking about it some, a subpackage is really
not so bad as long as it has a name that convey's some information.
`node` was chosen since this package deals with all the semantics of
operating a node in Kubernetes.
