Jbuilder: generate JSON objects with a Builder-style DSL

JbuilderTemplate#cache_if!

Conditionally caches the json depending in the condition given as first parameter. Has the same
signature as the `cache` helper method in `ActionView::Helpers::CacheHelper` and so can be used in
the same way.

Example:

  json.cache_if! !admin?, @person, expires_in: 10.minutes do
    json.extract! @person, :name, :age
  end
