Advanced forecast configuration

Configure advanced forecasting options in opscenterd.conf.

The following is currently configurable by adding a [forecasting] section to the opscenterd.conf file.

polyfit_degree = 2
Which degree polynomial equation to use in calculating the forecasting. (The default is three.)
range_multiplier = 3
In order to generate a meaningful prediction, historical data is analyzed for a period larger than the range being forecasted. (The default is three times larger than the range being forecasted.) For example, to forecast one month into the future, three months of data is analyzed.
required_data_percentage = 0.5
The percentage of the historical data required to be available. (The default is 50%.)
