The change Ib3c41a8bee349856d21f360595e41a9eafd79323 added a mechanism
to remove side-car containers before spawning a new one for the same
network.
For dnsmasq side-car, it matches on container statuses Exited
and Created, while all remaining containers match on Exited only.
However if a node running side-car is shut down ungracefully, containers
end in Created status and wrapper script won't be able to start the
containers because they already exist.
This change goes only to Train because in current master (Ussuri) these
wrappers were replaced by ansible.
