storage: fill NVMe-oF gaps in non-interactive mode, HA config, and target VM setup

Add NVMEOF_NQN, NVMEOF_ADDR, NVMEOF_PORT to the non-interactive
detection guard so that answer-file deployment works for NVMe-oF.

Define NVMEOF_DOMAIN=12 in VDSMConstants and NVMEOF in
StorageDomainType for consistency with engine and VDSM.

Include nvmeof_address, nvmeof_port, nvmeof_nqn, nvmeof_host_nqn,
and nvmeof_dhchap_key in hosted-engine.conf template so the HA
broker can reconnect NVMe-oF storage after a failover or restart.

Pass all five NVMe-oF variables through to the ansible target-vm
role so the engine VM can be provisioned on NVMe-oF storage.

Part of the NVMe-oF/TCP storage domain feature.
