Use google-format-code instead of eclipse ? #663

Is there a way to use google-format-code instead of the eclipse formatter with vscode-java ?

At the moment i'm forced to use it with the SaveAndRun extension, but this has issues like me doing changes while the file is saved and having to reconcile the buffer as it tries to reload.

I could work on a PR for this if you give a few stating points on how to implement this, it would help ?

Thanks,
