As far as I can tell, based on the implementation in MockProvider
NotifyPods is called with the mutated pod. This allows us to
take a copy of the Pod object in NotifyPods, and make it so
(eventually) we don't need to do a callback to GetPodStatus.
This seems to avoid a race conditions where at pod informer
startup time, the reactor doesn't properly get setup.
It also refactors the root command example to start up
the informers after everything is wired up.
We still use it internally, but this does not need to be part of the
public API. Instead just have callers pass us the relevent listers and
we create our own resource manager.
* 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.
