[karabaralex]

steps to repro:

1. create a mongodb cluster at Atlas
2. get connection uri which looks like mongodb+srv://.mongodb.net/test?retryWrites=true
3. add this uri to rest-hapi config

      mongo: {
        URI: 'mongodb+srv://<some>.mongodb.net/test?retryWrites=true',
      },

4. npm start
