Description

As of now multiple endpoint contains the code to handle the amazon specific request id-s.

    setRequestId(OzoneUtils.getRequestID());
...
    return Response.ok().status(HttpStatus.SC_NO_CONTENT).header(
        "x-amz-request-id", getRequestId()).header("x-amz-id-2",
        RandomStringUtils.randomAlphanumeric(8, 16)).build();

I propose to handle the request id generation + adding it to the headers in one location which is transparent for all the rest endpoints.
