docker-amundsen.yml pegging to tagged versions (#166)

* uses tagged versions of the three amundsen services
* sets PROXY_ENDPOINT for the elasticsearch container
   which _should_ make it JustWork(tm) with docker-engine
   based setups. NOTE this requires the 1.0.2 version of the
   search service container
* similarly sets PROXY_HOST for neo4j
