This causes resource leakage in Tempest. HA networks aren't cleaned, and, when
using limited VNI range, or VLAN range, Tests will start failing once limit is
reached.
Suggestion:
Introduce a cleaner to the tenant (not router!) cleanup code:
1. search for the HA network of this tenant (neutron net-list --tenant-id " ")
**note that the network has empty tenant-id but the tenant it belongs to is
part of the network name.
2. if exist, log a warning.
3. if CONF.network.cleanup_l3_ha: delete the network
This has to be logged and has to be turned off by default.

Title:
HA network remains even if there is no more HA router
Status in neutron:
Confirmed
Status in tempest:
New
Bug description:
Currently when the last HA router of a tenant is deleted the HA
network belonging to this tenant is not removed. This is the case in
the rollback of a router creation and in the delete_router itself.
