Preparatory data-model changes for NVMe-TCP support on the adaptive
storage framework. No behaviour change for existing Fibre Channel
users - the extra enum value, field, and getter/setter are only
exercised by callers that explicitly use them.
ProviderVolume.AddressType gains a NVMETCP value alongside FIBERWWN,
so adapters can declare that a volume is addressed by an NVMe EUI-128
(NGUID) rather than a SCSI WWN.
FlashArrayVolume.getAddress() produces the NGUID layout expected by
the Linux kernel for a FlashArray NVMe namespace:
00 + serial[0:14] + 24a937 (Pure 6-hex OUI) + serial[14:24]
which matches the /dev/disk/by-id/nvme-eui.<id> symlink emitted by
udev. Fibre Channel callers (addressType != NVMETCP) still get the
existing 6 + 24a9370 + serial form.
FlashArrayConnection gains a nsid field to carry the namespace id the
FlashArray REST API attaches to host-group-scoped NVMe connections,
when it is present.
