Cleans up docker registry by removing untagged manifests from the registry
This should fix the "FileNotFound" error experienced by some users when the registry has data corruption. Please test and let me know if it works as expected.
This should now work with token based authentication. Has been tested working on Harbor.
This should now support registries using S3 as a backend, and now also supports authentication.
Manifest lists supported, thanks to @joniw
Fixed error introduced in the last release that caused the script to not do anything (other than fail).
Fixed same manifest in multiple repos
