Change subject: This change fixes the sporadic connection refused errors after 
managix starts up an Asterix instance. This can mostly be seen during 
asterix-installer tests. The fix basically lets managix wait and listens 
through zookeeper for a signal from the cluster c

Patch Set 1: Code-Review+1

Ok, I understand better now. Thanks!

I agree that there in no intention of removing Zookeeper for Managix. However 
our other approach to starting the cluster node via YARN doesn't use Zookeeper 
(yet?). Also, I think that we might want to have another way to start an stop 
cluster nodes in the future that also might not use Zookeeper. So I think that 
introducing a dependency on Zookeeper is a little too much - especially given 
that we use Zookeeper in a very simple use case.

However, I think that this change clearly solves a problem for now and we can 
re-discuss the mechanism when it becomes necessary.
