Remove members.


<?php
$client = new Zookeeper();
$client->connect('localhost:2181');
$client->addAuth('digest', 'timandes:timandes');
$zkConfig = $client->getConfig();
$zkConfig->set("server.1=localhost:2888:3888:participant;0.0.0.0:2181,server.2=localhost:2889:3889:participant;0.0.0.0:2182");
$zkConfig->remove("2");
