> We have a few use cases where having zookeeper bound to specific port is very inconvenient.

> 1) Unit tests that run in parallel. 
> 2) Shared clusters where multiple giraph instances can run on the same machines. 
> In theory we don't need to know what port zookeeper will run on. In most cases we're
fine with any port available. 
> Picking any available port is currently supported by the server socket, but is not supported
in the code that parses zookeper configs (this code lives in zookeper). 
> We don't have to parse configs though, as we have a way to run zookeper in process. And
in that case we can have a full control on how zookeeper is initialized. 
> For this task I want to allow 0 as a port number for zookeeper. Which will allow us to
run zookeeper on any available port. And I will also remove "out of process" zookeeper, as
it clearly provides no benefits to us.  
> Note: it will still be possible to run external zookeper, if you have it running somewhere
as a service.
