Title: Output stage for elasticsearch

A basic output stage for elasticsearch that indexes and deletes single documents.

Some things to note:
* The stage uses a TransportClient to communicate with an elasticsearch cluster. The stage needs to know an index, a type, a list of nodes in the cluster (it does not do automatic discovery) and a cluster name.
* UPDATEs are handled as ADDs.
* Only has configuration for a single index (well, index alias) and a single document type
* Included test can be run with the maven verify goal
