project cleanup does not resolve ports with security groups

The project cleanup command is unable to delete Ports/security groups with security groups/ports still attached to them, and it does not resolve this situation properly

Environment:
- python-openstackclient version: 6.4.0

Steps to Reproduce:

The following terraform configuration deploys three resources:
- a network
- a port
- a security group, linked to said port

```terraform
resource "openstack_networking_secgroup_v2" "secgroup_1" {
  name = "secgroup_1"
  description = "My neutron security group"
}

resource "openstack_networking_network_v2" "network_1" {
  name = "network_1"
  admin_state_up = "true"
}

resource "openstack_networking_port_v2" "port_1" {
  name = "port_1"
  network_id = openstack_networking_network_v2.network_1.id
  admin_state_up = true
  security_group_ids = [openstack_networking_secgroup_v2.secgroup_1.id]
}
```

When trying to remove these resources it fails to do so, with the following error:

openstack.exceptions.ConflictException: ConflictException: 409: Client Error for url: https://url:9696/v2.0/security-groups/84b9793c-c970-476f-a581-47b872a06a04, Security Group 84b9793c-c970-476f-a581-47b872a06a04 in use.

Expected Behavior:
Ressources should be removed

Actual Behavior:
Security groups are not successfully remove when attached to a port.
