> 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.
