cloud-init status broken in groovy lxd containers

Status changed to 'Confirmed' because the bug affects multiple users.

This is also causing the docker.io autopkgtest failures in g, as the docker.io test 'docker-in-lxd' does:

+ lxc exec docker -- cloud-init status --wait
...........................
status: error

which fails the test.

This landed in https://github.com/canonical/cloud-init/commit/3d06abc2e0017436dadbf9c26fefa9f95368db9a, and I have since uploaded a new cloud-init package to groovy; it should migrate shortly.

This bug was fixed in the package cloud-init - 20.2-94-g3d06abc2-0ubuntu1
