// Associates one or more faces with an existing UserID. Takes an array of FaceIds
// . Each FaceId that are present in the FaceIds list is associated with the
// provided UserID. The maximum number of total FaceIds per UserID is 100. The
// UserMatchThreshold parameter specifies the minimum user match confidence
// required for the face to be associated with a UserID that has at least one
// FaceID already associated. This ensures that the FaceIds are associated with
// the right UserID. The value ranges from 0-100 and default value is 75. If
// successful, an array of AssociatedFace objects containing the associated FaceIds
// is returned. If a given face is already associated with the given UserID , it
// will be ignored and will not be returned in the response. If a given face is
// already associated to a different UserID , isn't found in the collection,
// doesn’t meet the UserMatchThreshold , or there are already 100 faces associated
// with the UserID , it will be returned as part of an array of
// UnsuccessfulFaceAssociations. The UserStatus reflects the status of an
// operation which updates a UserID representation with a list of given faces. The
// UserStatus can be:
// - ACTIVE - All associations or disassociations of FaceID(s) for a UserID are
// complete.
// - CREATED - A UserID has been created, but has no FaceID(s) associated with
// it.
// - UPDATING - A UserID is being updated and there are current associations or
// disassociations of FaceID(s) taking place.
