Implement DMI Registration (NCMP-Side)

Implementing registration of CM-Handles to NCMP from DMI

CM Handles are Written to fragment tables

Moved NetworkCmProxyDataServiceImplSpec.groovy as it was not in the same
package as the class it was testing. Meaning it didn't cover this when
it came to code coverage

Have included Json structure validation also within open api

Deprecating old API's along with old API Methods

Issue-ID: CPS-442

Change-Id: I819b9bf65280b1d968d3b75ca5ef2f9eb5617579
