Add two more elasticsearch nodes.
* manifests/site.pp: List the two new elasticsearch nodes in the appropriate lists. * modules/logstash/manifests/elasticsearch.pp: Do not restart elasticsearch when config files change. Service restarts are costly and should be manually performed when necessary. Otherwise puppet should simply update the config files. * modules/logstash/templates/elasticsearch.yml.erb: Update elasticsearch config with new cluster topology. Increase memory available for indexing. * modules/openstack_project/manifests/cacti.pp: Add new nodes to cacti monitoring list. Adding two more elasticsearch nodes to relieve memory pressure (more nodes means fewer indexes per nodes which requires less memory to manage). And two more nodes gives us more disk to retain older indexes in. These new nodes should allow us to retain at least 3 weeks of indexed logs.
