Currently if we get an error during CmHandle registration (e.g. a cmhandle id already exists) the server returns an HTTP 500 response. Which indicates an unhandled exception instead of a bad request.

The response status should be changed to 2xx or 4XX.

The current Http Status: 500 Server Error including failed cm handles with Cps error code and text. 

How?

• The new HttpStatus code: TBD
• The new HttpStatus code will be applicable only for cm handle batch create operation handled in NetworkCmProxyInventoryController.java
• The methods that handle HttpStatus.INTERNAL_SERVER_ERROR should have warn level logging with the exception stack trace in NetworkCmProxyRestExceptionHandler.java and  CpsRestExceptionHandler.java classes.

Out of Scope

• There will be no change on the existing CPS error codes.
