Due to poor performance of commands such as docker system df in some environments, the check_mk_agent would be slowed down to the point of unusability. To address this, these sections have been extracted into the mk_docker_node agent plugin, allowing them to be run asynchronously.

If you update the agent and you need these sections, you will have to deploy the plugin to continue monitoring docker node information.
