[Bug 1842937] [NEW] Some ports assigned to routers don't have the correspondent routerport register
Public bug reported:
When running a few subnet detaching from router and deletion, some
subnets are not possible to be deleted with this error:
$ openstack subnet delete e81929f6-25ea-45c2-89b5-ff94afd7136a
Failed to delete subnet with name or ID 'e81929f6-25ea-45c2-89b5-ff94afd7136a': ConflictException: 409: Client Error for url: http://10.0.0.104:9696/v2.0/subnets/e81929f6-25ea-45c2-89b5-ff94afd7136a, {"NeutronError": {"message": "Unable to complete operation on subnet e81929f6-25ea-45c2-89b5-ff94afd7136a: One or more ports have an IP allocation from this subnet.", "type": "SubnetInUse", "detail": ""}}
1 of 1 subnets failed to delete.
After checking the ports in that subnet, only the router_interface port is left behing (but in DOWN status):
$ openstack subnet show e81929f6-25ea-45c2-89b5-ff94afd7136a

Trying to detach that subnet from router does not return any error, but if run with '-vvv' the next appears:
$ openstack -vvv router remove subnet 33114251-4771-490a-bd7b-10a51e017719 e81929f6-25ea-45c2-89b5-ff94afd7136a 2>&1 | grep "has no interface"

And checking the database it is true that it is NOT there:

However, by checking the router we get it is there:
