Log namespace and project rename events for Geo log
For the Geo log, we need to add events for when projects and namespaces get renamed. For each project, we will need to log the previous and the current name.
For each namespace, we will need to add all the projects affected as well.
On the secondary, we may need to look at which paths are changed and determine which projects need to be marked dirty.
