/**
 * A simple HttpLogger inspired by morgan
 *
 * The message will be printed over info() method if the req.end() incl: send, json, sendStatus, sendFile (non streaming), gets executed.
 *
 * Warning: The peformance will be degraded when you use the module even when the logging level (in case you use the built-in Logger) is set to false
 * it'd be better if this middleware is used in development mode only
 *
 * Passing a custom console which must be extended from ILoggerProvider (@default console)
 *
 * If you want to use global application logging setting, use the code below
 *
 * @example
 * import rex, { getLoggerInstance, httpLogger } from 'rex'
 * const app = rex();
 * app.use(httpLogger(getLoggerInstance()))
 *
 * @param opts
