History
Slawek Kaplonski 93d9d6bbba Ensure there is always at most 1 dvr fip gw port per agent and network 
In patch [1] there was introduced simple lock for creation of
DVR agent's floating IP gateway ports for network to avoid races
and creation of duplicated ports for one agent and one network.

This fix from [1] works in simple examples with only one neutron-server,
so it helped e.g. in CI but it wasn't proper fix for production
deployments which are much bigger and have more neutron server api
workers.

So this patch introduces constraint on database level so this works even
across cluster with multiple neutron-server api workers.
