Change `to_python` and `to_url` to be class methods on path converters

Hi, I ran in to the situation of wanting `to_python` and `to_url` be decorated with `@classmethod` to avoid having to declare an additional (kind of no-op) class with those 2 methods. Given that I have a couple of custom python data structures that can be encoded into path params, it would be

A generic cache decorator around low level cache api

Usually, I need to construct a simple cache pipeline to optimize database access using low-level cache API (django.core.cache). I think we could use a decorator as such to ease this process: cached_context(key, *, timeout, cache) I know higher-level utilities exist such as cache_page, however

Re: Make timeout property for PasswordResetTokenGenerator
