docker-cleanup is a command to perform precommit's Docker cleanup functionality outside of patch and build testing.
It is designed to be run as a regularly automated job on CI systems that do not have their own Docker cleanup
facilities. It is built from the perspective that nothing on the system is permanent. It supports many of the same
options as test-patch's docker-mode. Please see that page for more details.
Executing docker-cleanup with no additional options will perform the same work as the --robot option.
