Preparing for Kinetic Sync 2017-06-26

I’ve identified two more small regressions.

robot_controllers had some references to indigo in the debians which I have rolled back:

https://github.com/ros/rosdistro/pull/15419

And rosjava_messages on Jessie AMD64 looks to be having an issue with ssl certificates.

https://github.com/rosjava/rosjava_messages/issues/29

My best guess is that this is an openjdk issue so I won’t block our sync on this. And robot_controllers appears to be rebuiliding successfully so I will plan to release when that’s cleared.
