> 
> Firstly, each DNN filters duplicate DNN_COMMON_OPTIONS, which should
> be the common options of backend.
> 
> Secondly, backend options are hidden behind the scene. It's a
> AV_OPT_TYPE_STRING backend_configs for user, and parsed by each
> backend. We don't know each backend support what kind of options
> from the help message.
> 
> Third, DNN backends duplicate DNN_BACKEND_COMMON_OPTIONS.
> 
> Last but not the least, pass backend options via AV_OPT_TYPE_STRING
> makes it hard to pass AV_OPT_TYPE_BINARY to backend, if not impossible.
> 
> This patch puts backend common options and each backend options inside
> DnnContext to reduce code duplication, make options user friendly, and
> easy to extend for future usecase.
