------------------------------------------

             Summary: Use endpoint id as path in zookeeper
                 Key: ARIES-1778
                 URL: https://issues.apache.org/jira/browse/ARIES-1778
             Project: Aries
          Issue Type: Improvement
          Components: Remote Service Admin
    Affects Versions: rsa-1.11.0
            Reporter: Christian Schneider
            Assignee: Christian Schneider
             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 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.
