Hope new version

[HW-Chao Wang]

Hello, ratis community :
I am the iotdb committer. At present, iotdb relies on ratis, but there are some 
bugs in ratis that need to be solved. We are very eager to release the next 
version of ratis. At the same time, I am also an employee of Huawei. We are 
also using this product. we hope to see the release of the next version.
Thanks
