Cache: multiple variants of a resource now can be stored.
If a variant stored can't be used to respond to a request, the variant
hash is used as a secondary key.
Additionally, if we previously switched to a secondary key, while storing
a response to cache we check if the variant hash still apply. If not, we
switch back to the original key, to handle cases when Vary changes.
