title: Access Stage results in Workflow/ Pipeline plugin
body: <p>I have a pipeline with different stages. I want the current job to check how many stages have passed in the previous build and log it in the console? </p>
  
  <p>Consider this is my current pipeline</p>
  
  <pre><code>node(){
   stage "1"
   do something
  
   stage "2"
   do something else
  }
  </code></pre>
  
  <p>I want a groovy script to give my something like this</p>
  
  <pre><code>println currentBuild.previousBuild.getStage("1").result
  </code></pre>
  
  <p>The purpose of my code is track successes &amp; failures in different stages across my builds. Are there any alternatives to this approach? </p>
