added awsboxen

This is a first draft of an awsboxen stack. It includes:

* IDP server
    * awsbox instance
    * points to RDS and ElastiCache
    * DNS name idp.profileinthecloud.net
* Log server
    * bare Amazon Linux
    * running ElasticSearch and Kibana is still TODO
    * DNS name logs.profileinthecloud.net
* RDS Database
* ElastiCache
* IT WORKS!
