Subject: Retrieve tag / tags value from query or request

It allows to request to delete a tag using query string instead of body parameter (which seems to be the standard).
Instead of breaking the previous behavior, I used a generic way to retrieve parameter (which looks into request attributes, query parameters and request parameters)
