Pin Nebius spot price at provisioning time - #4328
Merged

Conversation
Starting October 8, Nebius is introducing Dynamic Spot pricing for preemptible VMs. The price can change for existing instances during their lifetime. To prevent the price from increasing above the one `dstack` shows, `dstack` now caps the price at its current value at provisioning time using a pricing policy. If the price grows above the cap, the instance is interrupted by Nebius. The actual price may still drop below the one `dstack` shows. Preemptible L40S is still sold at a flat rate and is exempt from pricing policies. Full support for Nebius Dynamic Spot pricing (tracking the current price and showing it in `dstack`, user-specified caps, etc.) may be added later upon request.
