Comment 3 for bug 1827465

Additional info: When I changed a vip, I expected that to cause a relation-changed and roll the new VIP through the shared-db relations - however, the config files in Nova didn't change at all.

Also; in the nova_api database, the cell_mappings table contains a database_connection field which has the connection string for the cell db - if the password or VIP changes, this field is unaffected.
