Upgrade VPS plan

/vms/:vm_id/resize

Only upgrades are supported: CPU resources, RAM, disk and included traffic cannot decrease. Omit cpu_percent to keep the current share. The surcharge covers the remaining paid calendar periods at current plan prices with their originally purchased term discounts. paid_until does not change. expected_amount_usd is the maximum accepted surcharge, since it may decrease with time.

Send a unique Idempotency-Key for each intended action. If the response is lost, retry with the same key and unchanged parameters; do not create a new key for the same purchase.

HTTP 202 accepts the request; it does not confirm completion. Save the order_id or operation id and check its status.
