Public bug reported:

neutron-netns-cleanup cleans all DHCP resources by invoking a command on
the DHCP driver. However, in the L3 agent case, it merely tries to
remove the router namespaces. Any child processes that we've added over
the years (Specifically metadata proxy, radvd, keepalived at this point)
are not cleaned up. I think that netns-cleanup should remove any routers
on the system the same way we remove DHCP resources, by invoking a
method on a L3 agent instance.
