nvme: add NVIDIA plugin for NVMe SNAP controllers
SNAP technology is supported on NVIDIA Mellanox BlueField DPU family
and combines a unique hardware-accelerated virtualization of NVMe
devices with the advanced networking and programmability capabilities of
the BlueField SmartNIC.
Add initial vendor specific parsing for id-ctrl command of NVMe SNAP
controllers.

Read system UUID from DMI and merge hostnqn generation functions
Both fabrics.c and the 'gen-hostnqn' command contain functions
to generate a default host NQN. Needless to say, both are different.
_And_ we have the script 'nvme-gen-hostnqn' to read the host nqn
from the system UUID, implement yet another way.
This patch merges all of these functions, and implements a hierarchy
in generating host NQNs:
- Try reading system UUID from /sys/firmware/dmi/entries
- Try reading systemd-generated UUID
- Generate a random UUID

nvme-topology: have list-subsys print only controllers with attached namespace
When running list-subsys on a specific namespace, we output all the
controllers that belong to the subsystem regardless if the requested
namespace is actually attached to them.
Example:

nvme-subsys0 - NQN=nqn.2016-01.com.lightbitslabs:uuid:07cfffe6-5a4f-4151-b663-e13cf835609b

This output is somewhat confusing and makes the user think the namespace
is actually attached to all of these controllers, instead we want the
output which provided by the change introduced here:
Do the same trick as we do in scan_subsystems, we add the ctrl to the
topology if either ns_instance wasn't passed (see all controllers) or
it was pased _and_ the controller has this namespace is attached to
the controller (to do that we add nsid down the call chain for that).
