To address Mitchell's recent announcement (https://gist.github.com/mitchellh/90029601268e59a29e64e55bab1c5bdc), and as already done with Vault (hashicorp/vault#24239), we need to move Terraform from mitchellh/cli to the hashicorp/cli fork.

Commands to generate:

$ find . -name "*.go" -type f -exec gsed -i -e 's/mitchellh\/cli/hashicorp\/cli/' {} \;
$ for x in `git status -s|awk '{ print $2}'`; do gofmt -w $x; done
$ go mod tidy

Target Release

1.7.x
