Nightly trigger status checks too often

[z64555]

If the config.yml.example is anything to go by, the config["monitor"]["check_interval"] is too long with 20s, I feel like a 1m or 5m interval is more sensible.

This is mainly due to the limit of REST API calls that can be made. Authorized users of course do have a much higher limit than unauthed, but it is still there.
