This makes sure the update function works correctly after the pod
is running if the podspec is changed. Upon writing the test, I realized
we were accessing the variables outside of the goroutine that the
workers with tests were running in, and we had no locks. Therefore,
I converted all of those numbers to use atomics.
* Fix error handling for delete pod
- Error handling was looking for a k8s error from the provider, but
providers should be using errdefs.
- Error handling was returning early if pod was not found and deleting
from k8s in all other cases.
* Don't run unit tests twice
* 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.
