Change VPS plan

Preview or commit a VPS plan change. Get {id} from GET /api/v2/vps data[].id. First call GET /api/v2/vps/{id}/actions/upgrade; send availablePlans[].slug as productSlug. This route changes the plan only. To change option values such as bandwidthGb without changing plan, use POST /api/v2/vps/{id}/actions/config. Unsupported fields such as productId, resources, draftId, send, or estimate are rejected.
