@tennix PTAL

[jlerche]

I don't think any of the scripts do anything fancy, we should be able to do terraform 0.12upgrade and get it running without too much effort. I will be upgrading the GCP one at the same time as fixing #522

GCP is upgraded now. #616 upgrades AWS, please re-open this issue if you have any more problems.
