Upgrading to express logger versions

Upgrading to version 1.0.0+

• Middlewares now are exported as functions, so this is invalid:

app.use(expressRequestIdMiddleware);
app.use(expressMiddleware);

Instead, starting from 1.0.0 you should use this as functions:

app.use(expressRequestIdMiddleware());
app.use(expressMiddleware({ loggerFn: logger.info }));
