Support deploy in k8s

[zheng1]

What would you like to be added:

Provide an easy way to install into users' own k8s environment

• [x] kubeeye docker image update
• [x] gcr.io needs to be replaced
• [ ] documentation about how to access kubeeye's webpage
• [x] helm chart

I think we should unify the way users use.

1. use cli to output results
2. use the web interface to view the results visually

These two ways to build binaries separately and both need to support multiple architectures
