---------------------------------------

This needs some change in Ratis contract as well, right? I don't see a clear way of asking a RaftPeer whether there is a leader in XceiverServerRatis.

> Ozone pipeline on restart start in allocated state, they are moved into open state after all the pipeline have reported to it. However this potentially can lead into an issue where the pipeline is still not ready to accept any incoming IO operations.
> The pipelines should be marked as ready only after the leader election is complete and leader is ready to accept incoming IO.
