    ZOOKEEPER-2940. Deal with maxbuffer as it relates to large requests from clients

    This PR covers the other part of Jute buffer monitoring which relates to client response
sizes.
    
    `jute.maxbuffer` is often set too small or the default (4MB) value is not enough to receive
large responses from the server which causes the client unable to operate. e.g. `getChildren()`
on a node which has lots of children or execution of a large multi.
    
    These new metrics lets operators to monitor the size of generated responses to get an
idea on how to properly set client's `jute.maxbuffer`.
