Sanders for deployment

Workflow after AMI has been built for the version you want to deploy:

1. sanders create creates a launch configuration based on a selected AMI (created via Boxfuse/Packer)
2. sanders deploy deploys ONE instance with the version specified.
3. sanders confirm once we have verified that the new application is working well, it will deploy N instances.
4. sanders sunset to sunset the previous version. Only sunset when all new instances are up and running.

To deploy the app to our canary environment, run the command sanders canary. It will kill the current instance and spin up the new version.

⚠️ Important: sanders canary is NOT HA, there will be downtime between killing the old instance and spinning up a new one.
