This is where I am concerned something is broke with Quantum. It appears it has an issue creating this br-tun using ovs-vsctl. And what I am concerned about is that the br-tun is not getting created, but it is getting a new ID in the database, so when the second part tries to attach the routers to this bridge, it is getting the wrong ID.
Any thoughts would be appreciated. I wanted to hand this cluster over to our devops team today, and this is the only hangup.

Also check dhcp_agent.ini and l3_agent.ini. I couldn't find a related packaging bug but others following the docs have run into this on ubuntu.
