> Currently we use a quite complicated and not completely correct way to create zookeeper
nodes for endpoints.
> Below the base path we use the fully qualified interfacename and below the endpoint id
as path. 
> This creates several problems:
>  * To listen to changes we need to create nodes in zookeeper for every interface that
is requested as a service. So we end up with many nodes for non remote services.
>  * As an endpoint may have more than one interface we then end up with more than once
endpoint for it in zookeeper. When the endpoint changes this results in multiple change events
created
> So I propose to change this to a much simpler scheme by simply using the endpoint id
as a path in zookeeper. This will make it much easier to listen to changes and also will cause
less nodes to be created in zookeeper.
