Bug description:
The LXD 2.0.11 SRU in xenial broke pylxd and hence broke Launchpad
builds, as visible here:

AttributeError: 'Container' object has no attribute 'description'
I initially thought this would require reverting LXD, but on
inspection it's just adding some new attributes and it's really not
its fault that pylxd is unnecessarily strict. This was fixed in pylxd
upstream a while ago (https://github.com/lxc/pylxd/pull/234), and the
fix is in 2.2.4 so >=artful is already fixed. zesty in principle
requires the fix but I can't actually reproduce the bug there, so it's
probably best to leave it alone for the time being. However, xenial's
pylxd is currently broken.
[Test Case]
>>> from pylxd import Client
>>> client = Client()
>>> container = client.containers.create({"name": "test", "architecture":
"x86_64", "profiles": ["default"], "source": {"type": "image", "mode": "pull",
"server": "https://cloud-images.ubuntu.com/releases";, "protocol":
"simplestreams", "alias": "xenial"}}, wait=True)
>>> container.start(wait=True) # should produce no exceptions
[Regression Potential]
The fix is to the code that marshals objects between the LXD server
and the Python client code, so anything around there could in
principle go wrong. I think running launchpad-buildd against it ought
to exercise it fairly well.
