LXD container inside LXD machine stuck in "pending"

[Jordan Barrett]

Deploy a bionic charm on LXD:
    juju deploy tiny-bash --to lxd --series bionic
This will start a new bionic machine and a bionic LXD container inside this machine. The bionic machine starts correctly, and the container seems to start, but the container's state is never set to "started". It gets stuck in this state:
----------------------------------------------------------------
Machine State Address Inst id Series AZ Message
0 started 10.120.49.53 juju-1bf0b8-0 bionic Running
0/lxd/0 pending juju-1bf0b8-0-lxd-0 bionic Container started
----------------------------------------------------------------

This is on
- Juju 2.9.37-ubuntu-amd64-1650771
- LXD 5.7-749a602
- Ubuntu 20.04.5 LTS

LXD version inside the machine is 3.0.3.

Just observed the same thing with a focal LXD container inside a focal machine. Inside this machine, the LXD version is 5.7-749a602.

And observed the same with jammy inside jammy. Clearly this is a far reaching issue.

The next 2.9.46 candidate release will not include a fix for this bug and we don't plan on any more 2.9 releases. As such it is being removed from its 2.9 milestone.

If the bug is still important to you, let us know and we can consider it for inclusion on a 3.x milestone.
