    [CURATOR-386] Allow listener to be passed in to PersistentNode

    This provides ability to hook into events from PersistentNode when a
    node gets created.  PersistentNode would then notify any registered listeners that the 
    node was created, along with the path created (useful when protection is used).

> I think it would be useful to allow a listener to be passed in to the PersistentNode that would notify when the new node is created. This is useful as some cases such as disconnect / reconnect or when an ephemeral node is deleted and recreated by PersistentNode. In this case, I would like to be able to listen to these even so I can do something like issue a watch on the node.  
> For example:
> ```
> public interface PersistentNodeListener {
>     /**
>      * Called on a persistentNode event when node is created
>      *
>      * @param path Path of the znode
>      * @throws Exception errors
>      */
>     void nodeCreated(String path) throws Exception;
> }
> ```
> I have a code change implementing this and can issue a pull request for this.
