Set up the test helper server

[LDiazN]

With the new test helpers implemented, we need a way to host them

The setup has the following requirements

• Reduce to the bare minimum the amount of proxies:

  • The echo test helper is not an http server, is a TCP echo server, and will hang when a connection is established until the client closes it with a timeout
  • The json test helper reads the headers and sends them back as json, so any proxy in the middle can mangle the headers. We want to reduce the exposure to unnecessary proxies as much as possible

• This test helpers don't require IPV6 so the can be deployed on AWS

Setup all the Terraform provisioning and Ansible setup to deploy this server
