When neutron is configures to have l3_ha, there will be networks created
which have an empty tenant id field. OVSDB (and NeutronNorthbound) need to
be able to handle it gracefully.

---

Add to local.conf:

enable_service q-l3
ODL_L3=False

[[post-config|$NEUTRON_CONF]]
[DEFAULT]
l3_ha = True

source openrc admin admin
keystone tenant-create --name=tenant1 --enabled=true 2> /dev/null

keystone user-create --name=user1 --pass=user1 \

keystone user-role-add --user=user1 --role=member \
--tenant=tenant1 2> /dev/null

TNT1_ID=$(keystone tenant-list 2> /dev/null | grep '\s'tenant1'' | awk '

{print $2}

')
