Tested patch manually
After starting LivyServer we can get Livy Server URI from ZooKeeper

> Livy Server discovery
> ---------------------
>
> Key: LIVY-616
> URL: https://issues.apache.org/jira/browse/LIVY-616
> Project: Livy
> Issue Type: Improvement
> Components: Server
> Reporter: Oleksandr Shevchenko
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently, there isn't a way to get Livy Server URI by the client without
> setting Livy address explicitly to livy.conf. A client should set
> "livy.server.host" variable and then get it via LivyConf. The same behavior
> if you want to use Livy with Zeppelin, we need to set "zeppelin.livy.url". It
> very inconvenient when we install Livy packages on couple nodes and don't
> know where exactly Livy Server will be started e.g. by Ambari or Cloudera
> Manager. Also, in this case, we need to have Livy configuration files on a
> node where we want to get Livy address.
> It will be very helpful if we will add Livy Server address to Zookeeper and
> expose API for clients to get Livy URL to use it in client code for REST
> calls.
> Livy already supports state saving in Zookeeper but I don't see that we store
> Livy server address somewhere. Before starting investigating and
> implementation I want to ask here about this.
> Please, correct me if I missed something.
> Any comments will be highly appreciated!
