Change:
- Newer docker versions report the same message whether or not a logout
actually happened.
- Determine change status from looking at the config instead if we can.
- This also allows us to restore check_mode in logout and re-enable that
test.
Test Plan:
- CI, re-enabled tests
Tickets:
- Refs 6248f2fb6f
