this fixes the config problem

2013-11-09 04:28:11 [DEBUG] Configuring plugin ansible for entry point aminator.plugins.provisioner │
2013-11-09 04:28:11 [WARNING] No class resource attributes and no namespace info, returning empty config                                                                                              

The plugin config that is loaded is basically '.'.join(plugin._entry_point, plugin._name)
For your plugin, entry_point is aminator.plugins.provisioner, _name is ansible, so you need aminator.plugins.provisioner.ansible.yml
