markevans/dragonfly — Issue #150: Outdated docs on Heroku caching

The documentation on Heroku says:

> We won't need Rack::Cache on Heroku because it already uses the caching proxy Varnish, which we can make use of

This is true for Heroku's Aspen and Bamboo stacks, but not the Cedar stack (and likely not in the future):

> The new HTTP stack does not include Varnish (a reverse proxy cache)
