title: How do I specify multiple hosts in OpenAPI (Swagger)?
body: <p>Right now my OpenAPI 2.0 YAML file has only one host URL:</p>
  <pre><code>host: petstore.test.com
  basePath: /
  </code></pre>
  <p>Can I use multiple hosts like this?</p>
  <pre><code>host1: petstore.test.com
  host2: petstore1.test.com
  host3: petstore2.dev.com
  </code></pre>
