TMP: DISABLE EC2 scripts

We still pssh to the instances and have them echo their
ENVSUBST variables, but they then exit.  This way we can
test that we can authenticate to the instances, that template
rendering works, and that all the other authentication
(S3, Fastly) works, without actually changing anything on
staging/production.
