Looking forward to update to OpenMMLab 2.0

Hello, this issue is intended to guide on how to upgrade from OpenMMLab 1.0 to 2.0.

I'm Vansin, the technical operator of OpenMMLab. Last September, we announced the release of OpenMMLab 2.0 at the World Artificial Intelligence Conference. We invite you to upgrade your algorithm library to this version, which can be used for both research and commercial purposes. If you have any questions, feel free to join us on the OpenMMLab Discord at https://discord.gg/amFNsyUBvm or add me on WeChat: van-sin.
