Adding two CloudFormation templates for setting up the Linkerd

[nathanpeck]

This adds two new CloudFormation templates that set up all the LinkerD resources automatically, without needing to have many manual steps as in the original getting started guide for ECS. Accompanying PR for https://github.com/linkerd/website/pull/34

Great feedback. I do like the idea of using the SSH tunnel to access those internal ports for the dashboard and viz. I'll modify the template to accept an SSH key name from the user's account when launching the cluster and include instructions for how to SSH tunnel to make a request.

Do you think it makes sense to send the request to the linkerd proxy via SSH tunnel as well? I did like the simplicity in the original doc of being able to just send a curl request to port 4140 on any machine, although in a realistic prod deployment I'm not sure if its best practice to open your port 4140 directly to the world.

@nathanpeck Good question. I think if we're already going to ask the user for their ssh key name, and tunnel for linkerd-viz on 3000, it's fine to also ask them to tunnel to port 4140.

Cool! I'm working on these changes today. I'm also going ahead and upgrading the Consul version to the latest, because I noticed that the Consul in the original getting started guide was kind of old and popping up an upgrade warning when you navigate to the Consul admin UI

Updates:

• Consul 1.2.3 instead of the older Consul 0.8.5
• Instead of opening ports to a static IP address, users are instructed to open a secure SSH tunnel
• Word wrapped the markdown
• Removed the old, no longer used task definition files, policy files, etc

Very nice! All updated according to recommendation!
