Elasticsearch fails to start on first run when duplicate entries in the cluster.initial_master_nodes variable are present, as they are all required during the initial bootstrapping. It is currently possible for duplicates to be present in this when nodes are forced to be master-eligible using elasticsearch_node_master: true due to the master node setting algorithm within data-node-variables. This commit ensures that all values within the Ansible master_nodes variable are unique, whilst keeping the total count of master nodes the same, preventing Elasticsearch from crashing during initial cluster discovery.
