title: Add two flags in Maven tag to SkipTests
body: <p>I´m using a ScalaTest plugin to execute some IT test.  I need to skip all the test(<code>Unit, IT</code>) in some pipelines, and they only use the flag <code>${skipTests}</code> so I need to use that flag for all my types of testing. In local sometimes I want just to execute, unit or IT test, but now having only one flag it´s not possible.</p>
  
  <p>Only comment the line in the plugin of the IT it would works but I dont like this error prone aproach(Someone will commit the comment line for sure)</p>
  
  <pre><code>                &lt;skipTests&gt;${skipTests}&lt;/skipTests&gt;
  </code></pre>
  
  <p>I was thinking that it would be great if I can use some sort of <code>OR</code> condition to set a new flag in my local executions as true and keep the other as false</p>
  
  <pre><code>            &lt;skipTests&gt;${skipTests} || ${skipItTests}&lt;/skipTests&gt;
  </code></pre>
  
  <p>Obviously this is not working, but I was wondering if someone know a way to do what I want.</p>
  
  <p>Regards.</p>
