Convert .awsboxen.json into easier-to-maintain YAML files
Script creation of basic cassandra cluster.
Refactoring the awsboxen deployment scripts.
Add basic loadtest scripting.
Include some basic loads-runner boxes in the awsboxen deployment.

This means we don't have to do the password-stretching at runtime,
giving much improved throughput on the loadtests.
