Use JSON5 for configuration files with comments. Now we can leave the available config in `config.default.json` without having to add weird instructions to remove the `xxx`, etc - https://www.npmjs.com/package/json5 - https://www.npmjs.com/package/nconf - https://github.com/indexzero/nconf/issues/113#issuecomment-69999413 |

Tracing
Run the app with the OpenTelemetry tracing.
npm run start -- --tracing
# or
npm run start-dev -- --tracing
Manually:
node --require './server/tracing.js' server/server.js
Traces are made up of many spans. Each span defines a traceId
which it is associated with.
