Description

When using the Mesos containerizer with a private Docker repository with --docker_config option, the repository might expire credentials after some time, forcing the user to login again. In that case the Docker config in use will change and the agent needs to be restarted to reflect the change. Instead of restarting, the agent could reload the Docker config file every time before fetching.
