Fix neutron client dict grabbing
Due to a bug in python3.13 [1] the following code will leads to an
emptied dict by the GC even though we hold a reference to the dict.
import gc
class A:
def __init__(self, client):
self.__dict__ = client.__dict__
self.client = client
class B:
def __init__(self):
self.test_attr = "foo"
a = A(B())
print(a.__dict__)
print(a.client.__dict__)
gc.collect()
print("## After gc.collect()")
print(a.__dict__)
print(a.client.__dict__)
# Output with Python 13
{'test_attr': 'foo', 'client': <__main__.B object at 0x73ea355a8590>}
{'test_attr': 'foo', 'client': <__main__.B object at 0x73ea355a8590>}
## After gc.collect()
{'test_attr': 'foo', 'client': <__main__.B object at 0x73ea355a8590>}
{}
# Output with Python 12
{'test_attr': 'foo', 'client': <__main__.B object at 0x79c86f355400>}
{'test_attr': 'foo', 'client': <__main__.B object at 0x79c86f355400>}
## After gc.collect()
{'test_attr': 'foo', 'client': <__main__.B object at 0x79c86f355400>}
{'test_attr': 'foo', 'client': <__main__.B object at 0x79c86f355400>
Our neutron client has this kind of code and therefore failing in
python3.13. This patch adds __getattr__ instead of trying to hold a
direct reference to the __dict__. This seems to work around the
problem.

This using Plucky Proposed - 25.04
nova-compute: 3:30.0.0+git2025030311.e6b8b051a9-0ubuntu1
This nova compute version is a snapshot of current master branch from
the Nova project, RC1 will soon be available:
https://review.opendev.org/c/openstack/releases/+/943941
This happens during testing with Tempest, in tests such as:
tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_network_basic_ops
Nova should successfully create a VM
Nova failed to communicate with neutron because of an attribute error
I've tested the same version of Nova using the Epoxy Cloud archive
from proposed, and it worked correctly.
