Merge pull request #3058 from edx/jibsheet/remove-elasticsearch-terraform

This code has moved to an es module in the terraform repo

terraform/README

-This directory contains various modules for building out infrastructure using terraform.
+This directory contains the remains of an original attempt at using terraform.
 
-The goal is to have modules here that represent reusable chunks of terraform and that teams can build
-their own infrastructure by gluing together modules they find useful.
+Future work has been moved to a new repository.  Work is planned to open source our terraform modules.
