I have implemented this on 4.1.1 and want to port it to master in four phases. the phases i have defined as subtasks of jira ticket CLOUDSTACK-1532. the first phase is out as a review request https://reviews.apache.org/r/12849/, I have not been getting any feedback for a while, so I suppose it is allright and will ask someone (probably Hugo) to commit it. thanks, Daan
