Merge pull request #2418 from edx/e0d/terraform

simple example to introduce terraform

terraform/README

+This probably makes the most sense in a private repository, but I'm adding it here toyp kick-off the Jenkins site-speed integration.  We can move it later.
+
+Note that I've included the tfvars file intentionally as an example, but this would typically be git ignored.
+
+Start by downloading and installing the terraform go binaries.  Run
+
+> terraform plan 
+
+from the sitespeed directory to see what would happen if this was run against and AWS account.
