Currently Artifactory calculates the value of 'latest' tag either based on SemVer or when the package was published. Both of these are incorrect.
As an npm user I want to be able to tag 3.0.0 as latest and 4.0.0-pre as next.
given version 3.0.0, npm publish should implicitly set 'latest' to 3.0.0
given version 4.0.0-pre, npm publish --tag next should set 'next' to 4.0.0-pre without affecting 'latest' (3.0.0)
