[DISCUSS] Integrated ICE

[zhongming hua]

Hey, community, I recently did a project to integrate ICE into dubbo. Now
open source, and intend to donate to dubbo, if you have any questions, you
can contact me directly or submit issues at the project. If the community
feels that there is no problem, I will merge this part into dubbo.
The project address is：https://github.com/CrazyHZM/dubbo-rpc-ice
