title: Swagger avoid removing common prefix
body: <p>How to skip removing the common prefix from modelsEnum name?
  I have got an enum with single value (in the future I will have more values) and swagger code gen plugin generates the class with enum <strong>CODE</strong> instead of <strong>AIRPORT_CODE</strong></p>
  
  <pre><code>properties:
    type:
      enum: ["AIRPORT_CODE"]
      description: the type of location that is identified by the value
  </code></pre>
