CPS-1401 Implement V2 of GET Data Node API
- Modified the GET Data Node API so it returns all the data nodes when xpath set to root "/" - Fragment Repository now returns a collection of Fragment Entities - Instead of returning only the first Fragment Entity now all fragment entities are returned when xpath is set to root - The Fragemnt Entities are further processed to a Collection of Data Nodes. As opposed to singular Data Node in current implementation. - Finally the DataRestController also returns a Collection of Data Nodes when xpath is set to root and valid data is present - Response body changed from JSON object to JSON Array. - Exception handling for invalid xpath and non-existing xpath is now done separately at persistence layer. - Refactored code against CPS-1422 - Deprecated getDataNode method from Service and Persistence layer - Modified V1 of Get Data Node API to use the getDataNodes method and get the first data node from the collection returned. - Modified NCMP to use getDataNodes method - NCMP still does not support multiple data nodes. It retrieves the first data node from the collection returned by getDataNodes Signed-off-by: arpitsingh <as00745003@techmahindra.com> Change-Id: I494a5740a53f65376d135fcb9f1e2e8900a2803e
