title: running the same task on multiple agents in my Jenkins declarative pipeline
body: <p>I have a block like:</p>
  
  <pre class="lang-groovy prettyprint-override"><code>stage('Clone on win10x64-b-ut') {
      agent {
          node {
              label 'win10x64-b-ut'
          }
      }
      steps {
          gitClone()
      }
  }    
  
  stage('Clone on win81x64-b-ut') {
      agent {
          node {
              label 'win81x64-b-ut'
          }
      }
      steps {
          gitClone()
      }
  }
  </code></pre>
  
  <p>I want to run the same task in somewhat like a loop by just changing the labels. I want to eliminate redundancy as much as possible.</p>
