> When building the basic framework for HBASE-19064, I found that the
> enable/disable peer is built upon the watcher of zk.
> The problem of using watcher is that, you do not know the exact time when all
> RSes in the cluster have done the change, it is a 'eventually done'.
> And for synchronous replication, when changing the state of a replication
> peer, we need to know the exact time as we can only enable read/write after
> that time. So I think we'd better use procedure to do this. Change the flag
> on zk, and then execute a procedure on all RSes to reload the flag from zk.
> Another benefit is that, after the change, zk will be mainly used as a
> storage, so it will be easy to implement another replication peer storage to
> replace zk so that we can reduce the dependency on zk.
