Copy chart to kubernetes/charts

[wbuchwalter]

Once #71 is in, we should also make a PR to kubernetes/charts.
This would allow the installation of the chart by just doing
helm install incubator/tf-job which would be even simpler.

The problem with moving the chart to incubator/tf-job is that it would introduce a manual step into our release process. Any time we wanted to do a release we'd have to wait for a PR to be approved.

Eventually, I'd like to automate releases so that we push a new chart and Docker image on each green postsubmit.

Pushing to incubator/tf-job might make sense once we reach v1 or possible v1beta1 and things stabilize.

Additionally charts are often out of sync partially cause by unresolved helm/charts#1471

@wbuchwalter Do you still think this is worth doing?

[wbuchwalter]

Let's discuss it again once we are at a stable v1.
We won't be making as much breaking changes then, so it should be okay if the chart on kubernetes/charts is not updated as often.
Also hopefully helm/charts#1471 will have progressed.

We do not support helm chart now.
