* Added a custom filter to append string to a string (btw jinja2 on CentOS 6.5 has no map()
* Moved most of the configuration to variables defined in /etc/ansible/hosts
* Configured both masters and real-workers1 to be monitored
* Using Python 2 for all code (since CentOS 6.5 comes with Python 2.6)
* Bugs: configures both master1 and master1.astroclust.uwc.ac.za. In gmetad.conf includes master1:port instead of full hostname (seems to be related to ansible nested host group setup)
