Broker new price adapter #4521

Also rename: AllowedRenewals -> PotentialRenewals to avoid confusion of future readers. (An entry in AllowedRenewals is not enough to allow a renewal, the assignment also has to be complete, which is only checked afterwards.)

Does not work with renewals as is - fix.

not on number of cores. I have to think a bit more about this, but I believe we will arrive have been sold at almost the base price

The old type was very misleading as an entry in `AllowedRenewals` does not mean that a renewal is actually allowed.

Left some questions and notes here and there but overall looking solid.

This PR includes three separate pallet-level changes as I see it:

Giving more scope to the PriceAdapter by removing restrictive logic from the pallet and allowing it to dictate the renewal price
Changing adapt_price to only consider price changes
Renaming AllowedRenewals to reflect its actual implementation

I am fully behind. Although I think that we should be adding more information to SalePerformance, rather than stripping it back to only the price. Including other metrics from the sale like cores offered and cores sold would achieve this without committing to 2.
I am not convinced by this approach, I think the new model that you're proposing here weakens the price finding mechanism in cases where we do not sell out, and would increase the time for the price to respond to market fluctuations -- both internal (demand for and perceived value of coretime) and external (DOT-FIAT volatility).
Even if I'm wrong, I think the work in 1 would allow more flexibility in the PriceAdapter would allow experimentation in the implementation without committing to it at the pallet level.
Good point, maybe we should reconsider where the completeness check happens. The check for a complete mask for a given workplan and full duration should probably happen before we put it in the AllowedRenewals at all, leaving it as a definitive list of cores that can be renewed. I think that's useful information to have in state.

Sweet, let's get it merged. Future models can add anything more general that is needed.
