title: How to run schema-registry in master slave mode
body: <p>As of now I am running schema-registry as a single node.
  To provide fault tolerance, I want to run schema-registry in master slave mode. One node for master and one node for slave.</p>
  
  <p>Do we need to add any extra property to identify a node as master?</p>
  
  <p>Please can any body share me the configurations(schema-registry.properties) for master and slave.</p>
  
  <p>Any help is appreciated.</p>
