Implement getDataNode(anchorName, xPath) in NF-Proxy

Added spring-boot-starter-validation instead of cps-ri.
Added test 'Data node without leaves and without children.' to MultipartFileUtilSpec groovy test
Created a method getNodeByCmHandleIdAndXpath(cmHandleId, cpsPath)
Added hardcoded value of NFS DataspaceName as: "NFP-Operation".
Issue-ID: CPS-172
