Replacement in tag names with req.params is not useful

[kapouer]

It just doesn't match how upcache tags are set w.r.t. express middlewares.

It would be more useful to configure upcache.tag with some filter(name, req) function.

Express "params" is useful for a single route, but tag usually applies to many routes at once.
