Chinese Language Support

[akaroml]

We have lots of Chinese developers. It would be great if we can provide a localized interface. This issue is to track the effort of building the localization story.
Supporting Chinese is a start. Once the solution is working, we can expand the support to other languages.

Here are the issues created to track the progress of related extensions:

• Java Language Server Chinese Language Support redhat-developer/vscode-java#716
