Backward Incompatible changes after GA

[Hanisha Koneru]

Hi All,

While updating Ratis version in Ozone, noticed some backward incompatible 
changes in Ratis. 
        1. Config key renames (example - rpcslowness.timeout -> 
rpc.slowness.timeout).
        2. Public interface method renames (example - RaftPeer constructor has 
been replaced with a builder, RaftClient async methods have been put behind 
AsyncApi)

Now that Ratis is GA, shouldn’t we maintain backward compatibility?

Thanks
Hanisha
