Org Billing Cycle / Predict Overage

[geoffreywiseman]

GitHub doesn't expose much information about the billing cycle in the API -- either the REST or the GraphQL, near as I can see.

The only thing I've found so far is a number of days left in the billing cycle in the storage resource.

This extension could in theory use this to roughly calculate what percentage of the cycle is done and how many minutes of actions usage there have been and if the actions usage is likely to go into billed minutes, and if so, roughly how many, and roughly what cost.

It can't be super accurate without better knowledge of the billing cycle, but it could be loosely useful.
