Public bug reported:

The FIP namespace is deleted when the agent receives an RPC message
'fipnamespace_delete_on_ext_net'
(https://review.openstack.org/#/c/230079/). This is simulated in some
DVR tests (Thus cleaning up the namespace), but not all. All of the DVR
'lifecycle' tests execute _dvr_router_lifecycle, which in turn executes
_assert_fip_namespace_deleted, that calls
agent.fipnamespace_delete_on_ext_net and asserts it succeeded. Any test
that creates a distributed router that is not a 'lifecycle' test does
not clean up the FIP namespace, this includes:

* test_dvr_router_fips_for_multiple_ext_networks
* test_dvr_router_rem_fips_on_restarted_agent
* test_dvr_router_add_fips_on_restarted_agent
* test_dvr_router_add_internal_network_set_arp_cache
* test_dvr_router_fip_agent_mismatch
* test_dvr_router_fip_late_binding
* test_dvr_router_snat_namespace_with_interface_remove
* test_dvr_ha_router_failover
