StaleDataError on ha_router_agent_port_bindings update

[John Schwarz]

Stacktrace: http://paste.openstack.org/show/539055/

There are a number of currently opened bugs that might deal with this, but they are clouded with information that might not be relevant. I will wade through them in the upcoming days to see if I can find something similar to the stack (though at first glance I didn't).

Also, this happened on stable/mitaka. It's interesting to see if this also happens on master. it reproduced while running rally's create_and_delete_routers with high (=10) concurrency.

I guess this is something new (I looked trough existing bugs), I don't see such error on scale env with Mitaka. I will try to reproduce it on virtual env with mitaka.

After discussion we decided to move this bug to Incomplete state: as this bug is not reproduced on master, it was not reproduced during scale testing with Mitaka and I was not able to reproduce it for Mitaka env with 3 controllers and 2 computes.
