Introduced inference engine configuration task API, which allows user to
set user desired inference engine and its device type for inference
request. Regarding this, this patch adds below itask interfaces,
	- setEngineInfo
      . Set user desired inference engine and its device type.
    - getNumberOfEngine
      . Get how many inference engines are available for a given task API.
    - getEngineType
      . Get inference engine type to a given index.
    - getNumberOfDevice
      . Get how many device types are available for a given inference engine.
    - getDeviceType
      . Get device type with a given index.
