Subject: [PATCH] [#31] refs: Define ContainerID message

Define ContainerID message in refs package. In the future, this structure can be
ported into messages in place of the container identifier field to maintain
format uniformity. Also, storing the identifier in a dedicated message will
allow, if necessary, to expand it with additional information without losing
backward compatibility within one version of the API.
