Provide an option to disable import ordering or customize order

[PatrickRen]

I'm working on a project (Apache Flink) using AOSP format but with customized import ordering. I manually set the order in Preferences | Editor | Code Style | Java | Imports | Import Layout, but google-java-plugin will override my settings when I use "Optimize Imports".

Is it possible to provide an option to disable the feature, or let users to customize the import order? Thanks!

Many teams use custom import ordering, but now this limitation drives us to use the 1.15.0 version. I hope this feature will come soon.
