Add a new header attribute for advanced logging information

[MephistosFaust]

Hi folks,
I have the following problem. The information which will be logged into the remote_client_id field in kibana are either a uuid or an info_user_id.

morgan.token("remote_client_id", function getRemoteClientId(
      request,
      response
    ) {
      let rcId = "";

      try {
        rcId = request.headers.customeruuid;

        if (request.headers[CUSTOMER_UUID]) {
          rcId = request.headers[CUSTOMER_UUID];
        }

        if (request.headers[AUTH_INFO_USER_ID]) {
          rcId = request.headers[AUTH_INFO_USER_ID];
        }

        if (request.headers[AUTH_REMOTE_CLIENT_ID]) {
          rcId = request.headers[AUTH_REMOTE_CLIENT_ID];
        }

        if (!rcId) {
          rcId = "unknown";
        }
      } catch (e) {
        rcId = "error";
      }

      return rcId;
    });

Both of this informations are a little bit miss leading, since both are not the real client Id.
I want to write the real client Id (from an oauth token in my case) into this log field.

Unfortunately I cannot use these header attributes and just fill it with another information because other services reliant on the right UUID and an info_user_id.

So the only way to solve that problem I can imagine is to ad another if-clause and extend the logic in the method above with a new header attribute. Something like this:

if (request.headers[AUTH_REMOTE_CLIENT_ID])
 {
          rcId = request.headers[AUTH_REMOTE_CLIENT_ID];
        }

Is this an option for you?
