> Use endpoint id as path in zookeeper
> ------------------------------------
>                 Key: ARIES-1778
>                 URL:
>             Project: Aries
>          Issue Type: Improvement
>          Components: Remote Service Admin
>    Affects Versions: rsa-1.11.0
>            Reporter: Christian Schneider
>            Assignee: Christian Schneider
>            Priority: Major
>             Fix For: rsa-1.12.0
> 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
> 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.
