After the aiodocker migration in #6415 some add-ons may have been missing IP
addresses because the metadata was retrieved for the container before it was
started and network initialized. This manifested as some containers being
unreachable through ingress (e.g. 'Ingress error: Cannot connect to host
0.0.0.0:8099'), especially if they have been started manually after Supervisor
startup.
To fix it, simply move retrieval of the container metadata (which is then
persisted in DockerInterface._meta) to the end of the run method, where all
attributes should have correct values. This is similar to the flow before the
refactoring, where Container.reload() was called to update the metadata.
