Start warmup for a dedicated IP
Start the warm-up ramp (provisioning to warming_up). The ramp never starts automatically. Only a provisioning IP can be started; a suspended IP returns 409. Starting does not check DNS: the IP carries mail only while dns_confirmed_at is set and the IP is in a pool that routes mail.
