Includes: * baseline Windows AMI * initial pass at Terraform configurations * OpenSSH for Windows Using OpenSSH is a lot nicer for Nomad developers than winrm would be, plus it lets us avoid passing around the Windows password in the clear. Note that now we're copying up all the provisioning scripts and configs as a zipped bundle because TF's file provisioner dies in the middle of pushing up multiple files (whereas `scp -r` works fine). We're also running all the provisioning scripts inside the userdata by polling for the zip file to show up (gross!). This is because `remote-exec` provisioners are failing on Windows with the same symptoms as: https://github.com/hashicorp/terraform/issues/17728 If we can't fix this, it'll prevent us from having multiple Windows clients running until TF supports count interpolation in the `template_file`, which is planned for a later 0.12 release. |

Terraform Provisioning
These scripts are copied up to instances via Terraform provisioning and executed after launch. This allows us to update the Nomad configurations for features that land on master without having to re-bake AMIs.
What goes here?
- steps that are specific to a given Nomad build: ex. all Nomad configuration files.
- steps that are specific to a given EC2 instance: configuring IP addresses.
These scripts should be idempotent: copy configurations from /ops/shared to their destinations where the services expect them to be, rather than moving them.
