Added logstash_twitter_filter_elasticsearch_kibana_geekmush.pmx

This template provides examples of several applications working together, and can also be used as a basis for any of the 3 applications individually.

At the base is a flexible ElasticSearch cluster configuration (usably scalable to 8 nodes with the example config), utilizing environmental variables and linking for the critical information to complete the ES configuration files.

Using the ES cluster is an example container showing how to implement the Twitter plugin on LogStash to search the Twitter feed for terms of interest.  That LogStash container finds the ElasticSearch cluster through links and environmental variables controlled via Panamax.

Finally, there is a Web UI container providing the Kibana front end running on an Nginx webserver - also, configured through the Panamax interface.
