Create an empty face list with user-specified faceListId, name, an optional
 userData and recognitionModel. Up to 64 face lists are allowed in one
 subscription.
 <br /> Face list is a list of faces, up to 1,000 faces, and used by [Face -
 Find
 Similar](/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395237).
 <br /> After creation, user should use [FaceList - Add
 Face](/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395250)
 to import the faces. Faces are stored on server until [FaceList -
 Delete](/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039524f)
 is called.
 <br /> Find Similar is used for scenario like finding celebrity-like faces,
 similar face filtering, or as a light way face identification. But if the
 actual use is to identify person, please use
 [PersonGroup](/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395244)
 /
 [LargePersonGroup](/docs/services/563879b61984550e40cbbe8d/operations/599acdee6ac60f11b48b5a9d)
 and [Face -
 Identify](/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395239).
 <br /> Please consider
 [LargeFaceList](/docs/services/563879b61984550e40cbbe8d/operations/5a157b68d2de3616c086f2cc)
 when the face number is large. It can support up to 1,000,000 faces.
 'recognitionModel' should be specified to associate with this face list. The
 default value for 'recognitionModel' is 'recognition_01', if the latest model
 needed, please explicitly specify the model you need in this parameter. New
 faces that are added to an existing face list will use the recognition model
 that's already associated with the collection. Existing face features in a
 face list can't be updated to features extracted by another version of
 recognition model.
