Set up UploadsLink on beta cluster

Added the security review as a blocker as that also blocks deployment to Beta Cluster (see https://www.mediawiki.org/wiki/Review_queue )

@greg Anything left that I could do except waiting?

@Rillke Get the security review on the Security Team's radar and ask them to put it in their review backlog (warning: they have a lot to do with a small team, they have to prioritize heavily).

Ah, @Legoktm pointed out it is on their list for this quarter already: https://www.mediawiki.org/wiki/Wikimedia_Security_Team/Goals_201516#Q4_.28Apr-Jun_2016.29

So yeah, wait for them to do it :)
