title: Skip running PITest in maven build
body: <p>I'm trying to run a maven build from command line and exclude PITest from running any mutations. Currently the reports are failing and we need to be able to give a parameter to ignore running the mutation tests or ignore the results and continue the build</p>
  
  <p>I've running with some parameters like <code>mvn package -Dpit.report=true</code> </p>
  
  <p>or <code>mvn package -Dmaven.report.skip=true</code></p>
  
  <p>This is the PITest setup in my pom</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;org.pitest&lt;/groupId&gt;
      &lt;artifactId&gt;pitest-maven&lt;/artifactId&gt;
      &lt;version&gt;1.1.10&lt;/version&gt;
      &lt;configuration&gt;
          &lt;timestampedReports&gt;false&lt;/timestampedReports&gt;
          &lt;mutationThreshold&gt;95&lt;/mutationThreshold&gt;
      &lt;/configuration&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;id&gt;report&lt;/id&gt;
              &lt;phase&gt;prepare-package&lt;/phase&gt;
              &lt;goals&gt;
                  &lt;goal&gt;mutationCoverage&lt;/goal&gt;
              &lt;/goals&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>The problem is that is is still running PITest and causing the build to fail</p>
