Remove maven property site url

In the last three commits, the site reporting feature got gradually decommissioned. This commit removes any remaining fragments in this regard. Remove the section distribution management from the profile clouds-project. The comment about incorrect links generated might have resulted from multiple invocations of the check style plugin. Previously the check style plugin got utilized at multiple sections (reporting section and profiles) and probably overlapping maven lifecycles.
