【原创】给实现dialog LifeCycleOwner fragmnet activity都齐了，再也不需要在onDestory进行取消操作了。

activity和fragment都有了，dialog不加一个怎么行呢？
什么是 LifeCycleOwner 建议自己百度，它可以用在livedata,AutoDispose 来实现自动取消rxjava任务等等，用途多多。
但是传参数却需要LifeCycleOwner ,dialog是没有的，于是我徒手写了一个。

用法

            Dialog dialog=new Dialog(this);
            DialogLifeCycleOwner dialogLifeCycle=new DialogLifeCycleOwner(dialog);
            //由于接管了onDismiss,因此需要监听则需要通过此方法来实现监听。
            dialogLifeCycle.setProxyOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(DialogInterface dialog) {
                    //dialog close
                }
            });
            LifecycleOwner owner=dialogLifeCycle;
            //AutoDispose的用法
            observe.to(AutoDispose.autoDisposable(AndroidLifecycleScopeProvider.from(owner))).subscribe(observer);
