ApnsConfig.Builder中addPayloadAps和addPayload内容相同。

[superinkfish]

原代码：

        public Builder addPayloadAps(Aps aps) {
            this.aps = aps;
            return this;
        }

        public Builder addPayload(Aps aps) {
            this.aps = aps;
            return this;
        }

两个方法内容相同。ApnsConfig.Builder中缺乏setAps()方法，addPayloadAps()和addPayload()方法容易让人觉得和参数payloadAps和payload相关，容易有误解。建议改为：

        public Builder setAps(Aps aps) {
            this.aps = aps;
            return this;
        }
