title: commitlint config-conventional - Add prefix for commit messages
body: <p>I am trying to implement <strong>commitlint</strong> for one of my repo so all the commit messages are standard. However, we have requirement to ADD JIRA ID as part of prefix. </p>
  
  <p>currently, commitlint format is as below </p>
  
  <pre><code>subject(scope): message 
  </code></pre>
  
  <p>I need as mentioned below </p>
  
  <pre><code>JIRA-ID: subject(scope): message 
  </code></pre>
  
  <p>following works</p>
  
  <pre><code>parserPreset: {
      parserOpts: {
           issuePrefixes: ['w{2,4}-[0.9]{2,4}']
      }
  }
  </code></pre>
  
  <p>However it validates that JIRA id should be at the end. someething like below </p>
  
  <pre><code>subject(scope): message JIRA-ID
  </code></pre>
