* Add enable_cache parameter to APIRequestHelper
Passing this parameter will not add the BYPASS_CACHE and DISABLE_CACHE
load flags to the request which were previously set for all requests.
* Add testcase for when enable_cache is set and not set
* Remove enable_cache option from Request method that does not use APIRequestOptions
* Add comment explaining APIRequestHelper::Request method will be deprecated
* Remove enable_cache parameter from Download method
Instead, we will create a new Download method that accepts an
APIRequestOptions parameter when there is a caller for it
