[FLINK-6192]reuse zookeeper client created by CuratorFramework
Now in yarn mode, there're three places using zookeeper client(web monitor,
jobmanager and resourcemanager) in ApplicationMaster/JobManager, while there're
two in TaskManager. They create new one zookeeper client when they need them.
I believe there're more other places do the same thing, but in one JVM, one
CuratorFramework is enough for connections to one zookeeper client, so we need
a singleton to reuse them.
