    Forbid substrings based on a regexp in name_filter middleware
    
    In comments from https://review.openstack.org/8798 it was raised that it
    might make sense to forbid some substrings in the name_filter
    middleware.
    
    There is now a new forbidden_regexp option for the name_filter
    middleware to specify which substrings to forbid. The default is
    "/\./|/\.\./|/\.$|/\.\.$" (or in a non-regexp language: the /./ and /../
    substrings as well as strings ending with /. or /..).
    
    This can be useful for extra paranoia to avoid directory traversals
    (bug 1005908), or for more general filtering.
