Title: Setting metrics interval seconds by `round_interval` configuration

The metrics interval is hard-coded as 3600. I know, this is 'HR'forecast.
But, I hope this intarval could be changed by config.

In this patch, we can set interval seconds by the config param
'round_interval'(default:3600).

If this patch is not match HRForecast's philosophy, please reject it.
