allow configuration of session timeout min/max bounds

Key: ZOOKEEPER-601
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-601
Project: Zookeeper
Issue Type: Improvement
Components: server
Affects Versions: 3.2.1
Reporter: Patrick Hunt
Assignee: Patrick Hunt
Fix For: 3.3.0
Attachments: ZOOKEEPER-601.patch, ZOOKEEPER-601.patch
ZK servers currently enforce a min/max boundary on client session timeout
relative to the ticktime setting, detailed here:
http://hadoop.apache.org/zookeeper/docs/current/zookeeperProgrammers.html#ch_zkSessions
In general there are good reasons for this however in some cases, in
particular with HBase region servers, we have seen a need to allow this bound
to be set differently (higher). The Sun jvm can GC pause for very long times
(in some cases we've seen 4 minutes even with the realtime gc.
It would be good to allow this bound to be set via configuration parameters.
Note: 4letterword and JMX integration would be needed.
