Add github action google-java-format or not

Now the java code's format use google style, but sometime a contributor maybe forget format the code.

**Describe the solution you'd like**
There is a github action Google Java Format https://github.com/marketplace/actions/google-java-format

This action can help us format the java code before pr merged.

Do we need to use it?

The historical java code maybe be formated too, need more investigation
