Add elasticsearch-jetty to elasticsearch Whirr recipe

[rjurney]

https://issues.apache.org/jira/browse/WHIRR-261

Whirr enables creation of elasticsearch clusters on multiple clouds with a single shell command. However, it lacks access control of any kind. Adding elasticsearch-jetty will dramatically increase the use of the whirr recipe, and elasticsearch-jetty and elasticsearch itself.

Coordinating with the whirr team to get this done would be awesome!

I've wrote the elasticsearch service for Whirr and I'm available to help as needed.
