Do not provide response body when apply-object is successful

When `replication.maxApiPayloadSize` is set to a significant
value(for example 100mb) returning full json payload as a
part of the HTTP response can impact the performance.
To avoid sending the payload back to the client skip response
body and return just the http status code.
