fabrics: Add support for volatile configuration
The fabric resources are global resources and as such should only
modified by one component. So far nvme-cli was the only component
managing connections. With the introduction of nvme-stas we need to
coordinate the access to these resources.
Introduce access coordination feature which allows the external software
to drop volatile configurations files into the /var/nvme directory.
When nvme-cli ls executed(e.g. via the udev rules), the execution
context is evaluated and only resources which belong the application are
considered.

nvme-print: fix wrong list-subsys output when ns are attached to different ctrls
If we list subsystem controllers not for a specific ns (user did not pass
a namespace device node), we cannot look at the first ns in the subsystem
to list because it may not be attached to all subsystem controllers.
We incorrectly assumes that subsystem namespaces (or at least the first of
them) are attached to all subsystem controllers.
Fix that by showing the multipath subsystem-list flavor only when the user
passed a specific namespace, and fallback to a simple controller list otherwise.

fabrics: prevent 'nvme connect' to well-known discovery NQN
Using 'nvme connect' to connect to the well-known discovery NQN
could result in a few problems with the current implementation:
1) It does not explicitly disconnect from the discovery subsystem
after usage, thereby leading to a spurious discovery controller
on the host.
2) Multiple 'nvme connect' invocations to the well-known discovery
NQN would result in duplicate discovery controllers on the host.
All this is already handled in 'nvme discover'. So it would be
better to avoid using 'nvme connect' to connect to the well-known
discovery NQN in the first place, and use 'nvme discover' instead
for the same.
