title: Choosing configuration file to start elastic cluster
body: <p>I have two-node cluster on one machine and one config file (elasticsearch.yml). Is it possible to create another .yml-config file and start every instance with different config-file? For example, i want run cluster on two ports (localhost:9200 and localhost:9201) on the same time.</p>
  
  <p>I can't find command-line API for starting elastic-cluster (config-file as an argument?).</p>
