CM Handle Registration Request Payload

Proposed Changes

Scenario	Endpoint	Current Response Code	Proposed Response Code	Comments

Scenario	Endpoint	Current Response Code	Proposed Response Code
Create CM Handle	POST /v1/ch	201 (Created)	204 ( NO_CONTENT )
Update CM Handle	POST /v1/ch	201 (Created)	204 ( NO_CONTENT )
Remove CM Handle	POST /v1/ch	201 (Created)	204 ( NO_CONTENT )
Create ,Update or Remove CM Handle in the same request	POST /v1/ch	201 (Created)	204 ( NO_CONTENT )

As we are using a common payload to handle the Create , Update and Remove operation hence there is a need to streamline the response code in case of successful execution of the request.

For other scenarios , please refer to the page for the exceptions and response codes which will remain as is.

    public ResponseEntity<Void> updateDmiPluginRegistration(
            final @Valid RestDmiPluginRegistration restDmiPluginRegistration) {
        final DmiPluginRegistration dmiPluginRegistration = convertRestObjectToJavaApiObject(restDmiPluginRegistration);
        networkCmProxyDataService.updateDmiRegistrationAndSyncModule(dmiPluginRegistration);
        return new ResponseEntity<>(HttpStatus.NO_CONTENT);
