* each log line is a json object * structured logging allows logs to be ingested by machines and the logs to be indexed and queried addresses #1105 * structured logging allows arbitrary properties to be appended to each log line, and ingestion of logs to remain robust * Structured logging provided by `pino` library * Add `express-pino-logger` dependency * Remove `debug`, `morgan`, and `morgan-debug` and replace with structured logging * `console.log` & `console.error` replaced with structured logging in backend * Remove `DEBUG` environment variable and replace with `LOG_LEVEL` - Note that there is a test which reads from a logged line on `stdout`. This is not robust, it would be better to use the childProcess.pid to look up the port number. * Log errors at points we explicitly send error to Sentry * Amend indentation of a couple of log messages to align indentation with others
