Supervisord can start already stopped container

We stop containers via supervisord api call.
Also we try to stop containers via docker api call due to
supervisord bugs. Sometimes supervisord starts stopped
container again. And new container can't be run due to
old one container already run. For workaround this supervisord
bug we switch configs before upgrade.
