Introduce an option to deny unsigned tags from entering a repository. This is useful in teams where members forget to sign their release tags.
It does not actually check whether the signature is actually complete or valid, it just checks for the beginning of a signature, as further checks would be too involved.
This effectively also denies un-annotated tags, as those are unsigned by definition.
