From: Lucas Alvares Gomes <lucasago...@gmail.com> In order for the CMS to know which Chassis a distributed gateway port is bond to, this patch updates the ovn-northd daemon to populate the Logical_Router_Port table with that information.
To avoid changing the database schema, ovn-northd is setting a new key called "hosting-chassis" in the options column from the LRP table. This key value points to the name of the Chassis that is currently hosting the distributed port.
