Bug#927673: src:zookeeper: new upstream release 3.4.14

[tony mancill]

Package: src:zookeeper
Severity: wishlist

This bug is to track progress and prevent duplication of effort related
to the latest 3.4.x ZK release.

I have refreshed all of the patches against the new upstream version and
am now taking a look at whether we should package Apache Yetus audience
annotations [1] or patch ZK around it.  Spotbugs is another new dependency
introduced in this version that can either be packaged or patched.

Cheers,
tony
