Failed to handle shared network senario

[hongbin]

Description
===========
Create a network that shared by all tenants. Create container from shared network in different tenants. The container will fail with docker internal error.

Reproduce
=========
$ source /opt/stack/devstack/openrc admin admin
$ openstack network create --share test
$ openstack subnet create --subnet-range 10.2.0.0/24 --network test testsubnet
$ zun run --net network=test nginx
$ source /opt/stack/devstack/openrc demo demo
$ zun run --net network=test nginx
$ zun show cdfa61e6-3764-4f47-ac11-8ea54a4394e6
...
| status | Error
| status_reason | Docker internal error: 500 Server Error: Internal Server Error ("IpamDriver.RequestPool: Another pool with same cidr exist. ipam and network options not used to pass pool name").
...

Note
====
The error is from kuryr-libnetwork. The fix could be either enhance kuryr-libnetwork or work around the issue in Zun. I don't have an exact solution in mind.

    Handle shared network senario

    Create a network that shared by all tenants. Create container from shared
    network in different tenants. The container will fail with docker internal
    error.

    Reproduce
    =========
    $ source /opt/stack/devstack/openrc admin admin
    $ openstack network create --share test
    $ openstack subnet create --subnet-range 10.2.0.0/24 --network test testsubnet
    $ zun run --net network=test nginx
    $ source /opt/stack/devstack/openrc demo demo
    $ zun run --net network=test nginx
    $ zun show cdfa61e6-3764-4f47-ac11-8ea54a4394e6
    ...
    | status | Error
    | status_reason | Docker internal error: 500 Server Error: Internal Server
    Error ("IpamDriver.RequestPool: Another pool with same cidr exist. ipam and
    network options not used to pass pool name").

    This bug needs to the depends-on patch in kuryr-libnetwork.
