title: mvn release:perform automatically specify scm tag that includes release version
body: <p>I would like to setup my maven release to run in batch mode, but I'm not a fan of the default scm tag <code>${artifactId}-${releaseVersion}</code>.  Instead, I'd like to simply tag it with <code>${releaseVersion}</code>; however, I'm unclear if such a property exists (ie. without the -SNAPSHOT suffix).</p>
  
  <p>I'd like the configuration to resemble the code below.  Is such a default tagging possible with the maven-release-plugin?</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;plugin&gt;
    &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
    &lt;artifactId&gt;maven-release-plugin&lt;/artifactId&gt;
    &lt;version&gt;2.0&lt;/version&gt;
    &lt;configuration&gt;
      &lt;tag&gt;${releaseVersion}&lt;/tag&gt;
    &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
