Add a qualityManagement goal

More and more projects use an external quality management tool. So it would be interesting to add a qualityManagement goal similar to the cim and issueTracking goals. With this goal, user could add this kind of configuration in his pom.xml:

<qualityManagement>
    <system>sonar</system>
    <url>http://host/sonar/myProject</url>
</qualityManagement>
