Enable prediction kernel and days_previous_auto by default

What's Changed

Major changes

Default changes:

Enable days_previous_auto by default

By default the entire previous days history (max of days previous) is used to compute future load forecasts, the exact selected days in days_previous will be ignored. If you want to revert to the old behaviour set days_previous_auto to false in apps.yaml.

Enable prediction_kernel by default

If there is a prediction kernel binary available it will be used by default, otherwise fallback to Python. If this causes any problems with you can set prediction_kernel_enable to false in apps.yaml
