Fangmin Lv updated ZOOKEEPER-3163:
----------------------------------
    Description: 
Previously, it needs to go through all the cnxns to find out the session to close, which is
O(N), N is the total connections we have.

This will affect the performance of close session or renew session if there are lots of connections
on this server, this JIRA is going to reuse the session map code in NIO implementation to
improve the performance.
