> This is related to jute.maxbuffer problems on the server side when Leader generates a
proposal that doesn't fit into Follower's Jute buffer causing the quorum to be broken.
> Proposed solution is to add the following new JMX Beans:
> 1. Add getJuteMaxBuffer to ZookeeperServerBean which monitors the current jute.maxbuffer
setting,
> 2. Add get last/min/max ProposalSize to LeaderBean which monitors the size of the latest/min/max
proposal.
