Add dry run parameter

[vpipkt]

Deleting package version cannot be undone*. It would be useful for users to have the ability to perform a dry run of the action, that would simply log the versions of the package that would be deleted. This would let users make sure the action is targeting the correct package versions before taking a permanent action.

*In some scenarios versions can be rebuilt.

Looking forward to this feature.

However You can restore old version. In versions view, there is a dropdown to choose from active and deleted versions.
