BOOKKEEPER-1061: BookieWatcher should not do ZK blocking operations from ZK
async callback thread
In some cases, the BookieWatcher can get the ZK event thread stuck. This
happens when a ZK blocking request is issued from a ZK callback thread.
We should decouple the blocking requests in a separate executor to avoid
deadlocking ZK client.
