Update domain registry proxy terraform annealing config

1) Change annealing target to watch for sandbox terraform config instead of test.
2) Delete terraform config for test project, as this project will be turned down.
3) Do not ask annealing to watch for alpha project terraform config, as we intend to change alpha regularly and manually.
4) Make terraform output display both service account email and client id.
5) Change canary node ports to 3100X, as 4000X is out of range for kubernetes.
