7.15+ support?

Hi David

I see that elastic pretty dramatically changed how plugins work starting at 7.10. The 7.10 branch you have does not work with 7.15.1 for sure, and I'm guessing it has a lot to do with the big list of breaking changes that happened starting at 7.10. I looked at breaking changes for 7.16 - it looks like they've finally settled things down. Do you think you may be getting back into this project soon?

Thanks
