Code Issues Proposed changes

Reverse proxy subset of elasticsearch API.

Browse Source 
It has been requested that we provide programmatic access to the
elasticsearch API in addition to the Kibana web UI. Do this by reverse
proxying http://logstash.openstack.org/elasticearch/$API_REQUEST to
http://elasticsearch.openstack.org:9200/$API_REQUEST.

The only values for $API_REQUEST that will be passed through are
_aliases, _status, and _search.
