Safely cleanup unused project images.

The command works according to special rules called cleanup policies, which the user defines in
werf.yaml (https://werf.io/documentation/reference/werf_yaml.html#configuring-cleanup-policies).

It is safe to run this command periodically (daily is enough) by automated cleanup job in parallel
with other werf commands such as build, converge and host cleanup.
