> Primary use case for /apps is many execution engines runs on top of YARN 
> example, Tez, MR. These engines will have their own UI's which list specific 
> type of entities which are published by them Ex: DAG entities. 
> But, these UI's do not aware of either userName or flowName or applicationId 
> which are submitted by these engines.
> Currently, given that user do not aware of user, flownName, and 
> applicationId, then he can not retrieve any entities. 
> By supporting /apps with filters, user can list of application with given 
> ApplicationType. These applications can be used for retrieving engine 
> specific entities like DAG.
