Some sites get curtailed, and it would be good to have a way to store this.

Typically site might get curtailed from a start and end date time, with a from and to time.
There may be serval curtailments happening at the same time, for example

*ignore Cosmic

The new table could have

• from_date
• to_date
• from_time_utc
• to_time_utc
• curtailment_kw
• linked to site

Need to becareful of the adjuster behaviour

We would need to

• make new sqlalchemy table
• Make migration for this table
• add function to get all curtailments for a site.
• add read and write route to india-api, users would only have access to there site. We might want a edit/delete route too
• add method to read curtailment in forecast and clip forecast
