Allow redeploy for "latest" docker tag in Nexus OSS

This is not possible. It does seem like a bit of an oddity given how the Docker format works. You can pop over to https://issues.sonatype.org/browse/NEXUS and file an issue about this functionality.

In sonartype version 3.21.1 this feature has been added. When the Disable redeploy policy is selected , we get new option: Allow redeploying the 'latest' tag but defer to the Deployment Policy for all other tags.
