Public bug reported:
### env ###
upstream code
DVR enabled
2 network nodes(l3 agent running in dvr_snat mode), 1 compute node(l3 agent
running in dvr mode)
2 tenants: admin and demo
### steps(by admin) ###
1, create external network and internal network, create subnets for the two
networks,
2, create a router(dvr default), attach external network as router gateway,
attach internal network as router interface;
3, verify router schedules success by "neutron l3-agent-list-hosting-router" or
"ip netns"
4, create a floatingip, boot a VM on internal subnet, and associate floatingip
to VM;
5, verify the dvr and floatingip related ports are created by "neutron
port-list -c device_owner"
6, run "neutron net-update EXTERNAL-NETWORK --shared False"
expected: "Updated network: EXTERNAL-NETWORK"
observed: "Unable to reconfigure sharing settings for network EXTERNAL-NETWORK.
Multiple tenants are using it."
### analyse ###
1, even all ports on EXTERNAL-NETWORK are belong to admin tenant, still fail to
update EXTERNAL-NETWORK shared attribute.
2, _validate_shared_update fails to work as expected for not all ports on
EXTERNAL-NETWORK have tenant_id.
3, following dvr and floatingip related ports have no tenant_id,
_validate_shared_update need be fixed for them:
fg: network:floatingip_agent_gateway
sg: network:router_centralized_snat
