Hello Helm

As we discussed on Helm weekly meeting of June 6, 2019, we tried set up a mirror of Helm Hub in China and it has been published here: https://developer.aliyun.com/hub

It's 100% free and open source, replaced all unavailable URLs in the chart, verify the chart by a Kubernetes cluster (CI), and publish chart to AppHub portal.

We highly encouraged you read its README about its details here: https://github.com/cloudnativeapp/charts, and feel free to let us know your ideas by sending issue or PR.

```
helm repo add apphub https://apphub.aliyuncs.com
```
and

Happy Helming in China!
