Is Embedded Raft storage maturity？

[xlj]

I notice this commit “We are excited to annouce the releases of the embedded raft storage in this version” in release v1.1.0, but in readme the "Is Embedded Raft storage" is still remark as "experimental". so Is Embedded Raft storage maturity? we can use it in product environment?

@xlj To be honest, I cannot say the raft storage is mature enough. But I would like to encourage users to use it because it won't bring other side effects to the running Kvrocks cluster if the controller is down. And you could simply reimport the cluster into a new one even if the data is damaged.
