Some systems - such as a mounted read-only CIFS filesystem - do not fully support chown, and chowning should be considered optional for cases when the host os has already taken care of permissioning. This commit allows users to disable chown by setting a property on the scheduler-docker-local plugin.
This can be useful in cases where a developer wishes to see what error messages are available for a failed deploy, but does not wish to spelunk around `docker ps -a` output.
Note that the logs are not made available once a further deploy is triggered, or after the containers have been garbage collected.
