Use a proxy managed log directory instead of docker logs

[sync-by-unito]

The proxy logs are currently managed by Docker and they are lost when a container is destroyed and recreated. https://datastax.jira.com/browse/ZDM-338 will allow us to change the automation so that it mounts a new docker volume and uses that directory instead of the docker logs directory which we don’t control. Therefore, this ticket depends on https://datastax.jira.com/browse/ZDM-338.

• Create directory and use this new directory to mount a docker volume with the log directory that is used by the proxy within the container.
• Set the new parameter introduced by https://datastax.jira.com/browse/ZDM-338 and make sure that parameter is used when mounting the docker volume for the log directory.
• Change playbook that retrieves logs to use the new directory managed by the proxy (and used as a docker volume) instead of the directory that is managed by docker.
