Public bug reported:

When creating a new loadbalancer with haproxy, and the VIP and member
subnets are different, the created lbaas namespace contains only the VIP
subnet, so the members are unreachable.

E.g.:
neutron lbaas-loadbalancer-show 8e1c193a-ab63-4a1a-bc39-c663f2f9a0ee
.

Note that the two subnets are different.
The created haproxy config is OK:

The member subnet is missing.
