Subject: [PATCH] Added a single snapshot time for GetResponse

The data collected for each individual path in the notification, may carry a different timestamp from other paths. In that case, there is no single view of the complete data for the list of paths in the GetRequest.  From a target's perspective the collection for a Subscribe request and a Get request is identical and only the mode of transport of those notification is different. The individual notification gives the timestamp of the collected data of the relevant path in a distributed environment. The target waits for all the individual collections to complete, pack it into a single Get response and send it.
With this change, we introduce a timestamp for the entire snapshot, attached when the collection is complete for all the paths and the packet is ready to be sent to the client.
