Not sure we can merge this just yet -- CI is showing that the new version of Go isn't vendored on CircleCI's side. Are there specific features we want out of 1.12.16 that would warrant a workaround, or should we just keep an eye out for when this is available in Circle?

[mkcp]

We'd need either a workaround (source go from not the circleCI image, or wait until a new image is available. (Is there an update stream from circle that we can watch to see when 1.12.16 would be built?)

You'll also need to update scripts in build-support, as well as i think the consul-releases project FYI:

$ git grep "1\.12\.13"
.circleci/config.yml:    go: &GOLANG_IMAGE circleci/golang:1.12.13

@mkcp mostly because it has security fixes for windows: https://groups.google.com/forum/m/#!topic/golang-announce/Hsw4mHYc470.
