A run_once task decides on a host without the context of conditionals related to the task. The filter is done prior to evaluating any conditionals. Also, only the neutron-server neutron.conf has the database connection credentials as a security measure, so it is not able to execute the database migrations. This patch ensures that the database migrations are only run once, but are also executed wherever neutron-server is. It also adds multiple instances of neutron-server and neutron-agents to better test against problems of this nature happening again. Additionally, the patch uses the handlers for the offline migrations to ensure that neutron-server is only restarted once when a new tag is deployed.
