* Provides cached access to Nova Extensions with utilities to help
* with asynchronous data loading. The cache may be reset at any time
* by accessing the cache and calling removeAll. The next call to any
* function will retrieve fresh results.
*
* The enabled extensions do not change often, so using cached data will
* speed up results. Even on a local devstack in informal testing,
* this saved between 30 - 100 ms per request.
* @returns {Object} The service
