Add Panamax template for Spring XD distributed deployment

This template requires following bug fix:
https://github.com/CenturyLinkLabs/panamax-api/pull/192

If you are running the template before above fix is merged and released as a stable version make sure you add "/admin" command under kparikh_springxd_1 service

Spring XD Panamax template simplifies deployment of a distributed 6 container application to a single click deploy. Basically simplifying steps documented here [https://github.com/parikhkc/docker/blob/master/README.md] to search and run template from Panamax UI.
