Description

ZooKeeper 3.6.0 (soon to be released) has a number of internal changes that require significant changes to Curator. We should consider:

• Major version bump (5.0? 4.4?)
• Remove ZK 3.4 compatibility code - Curator 4.2.x can remain the supported version for 3.4 compatibility
• Should we remove the few Guava classes that have leaked into our public APIs? ListenerContainer has been deprecated for a version or two now.
• We can also remove the "Reaper" classes which are no longer necessary given Container nodes
• Remove Exhibitor support
