* Improve API4 initialization - Refactored openGraphDataCache to be inside app layer. - Moved the cache instance from global variable to be inside server. - Moved out the app instantiation from the global commands package to be instantiated on every call. Only the server instance is passed. - Moved InitLocal to be called from inside Init. ```release-note NONE ``` * Remove commented line ```release-note NONE ```
