Title: Expose memoizing cache proxy backend

@camilo @boourns @dylanahsmith I need to set the `instrument` value on the cache backend to start getting ActiveSupport::Notifications from the IDC cache backend. See: http://api.rubyonrails.org/classes/ActiveSupport/Cache/Store.html#method-c-instrument-3D

Is it ok if I make the thing accessible?
