Till Westmann has posted comments on this change.

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.
