ARIES-2200 Fix ZooKeeper concurrency issue that may close the wrong client

> Project: Aries
> Issue Type: New Feature
> Components: Remote Service Admin
> Affects Versions: rsa-1.16.1
> Reporter: Amichai Rothman
> Priority: Major
> Fix For: rsa-2.0.0
>
>
> The ZooKeeper discovery's ClientManager.stop() method calls
> zkClient.close() asynchronously, where zkClient is an instance field.
> However, by the time the async task runs, this reference could have already
> been replaced with a new client instance, e.g. in ClientManager.process
> handling of expired sessions which calls stop and immediately afterwards
> creates a new client. In such a case the close() call could inadvertently be
> invoked on the new client thus making it unusable, while leaving the old
> client unclosed.
