Access ElasticSearch running on simple server

[nateiam]

As a Herd Developer I want to access an ElasticSearch server so I can create and access an index on that server.

• ElasticSearch server is running on a server
• ElasticSearch creates a tiny placeholder index
• ElasticSearch services are accessible from all Herd application server instances
• Index is encrypted at rest and communication between Herd and ElasticSearch APIs are encrypted
• Authentication by either ELB/certificate or Apache
• Entire infrastructure to enable above is automated, repeatable and integrated into Herd deployment process - including creation of index.

Requirements for future stories, not to be included in this story:

• ElasticSearch deployed with 3 nodes
• ELB running in front of ElasticSearch
• ElasticSearch Node failover is tested
