Allow to keep query string during redirection through pyramid tween
Currently redirection_rule don't take query_string into account. It means that if we want to persist the query-string after redirection we have to write something like this:
if request.query_string:
return f"/mypath?{request.query_string}"
return f"/mypath"
It might be practical to add a keyword argument which would enable persistence of the query string to the add_redirection_rule function.
