fdc1278440 nvmf: simplify session and connection cleanup
The whole cleanup process is now started by
spdk_shutdown_nvmf_subsystems().  Each subsystem will clean up its
session, if any, and each session will clean up its connections.

40b0248602 nvmf: Remove cntlid from session
Subsystems only have one controller, so cntlid
is always 0.

a35de42e5d nvmf: Remove max io queue tracking from session
This was intended to track the number of NVMe device
queues per session, but there is only one hardware
queue per session. It was conflated with the number
of RDMA queues in several places as well.

64f6abea9c nvmf: Sessions now contain a list of connections.
There was an extra layer of indirection complicating
things for no reason. This removes it.

554701492c nvmf: simplify property handling
Create a list of valid properties with get and set callbacks (set is
optional to allow read-only fields).

Remove handling for fields declared as "reserved" in the NVMe over
Fabrics 1.0 specification.

Also simplify the vcprop structure to only contain the required fields.

bfa9931b3a nvmf: remove Create/Delete I/O SQ/CQ commands
These are not supported (and did not actually function) in NVMe over
Fabrics.  Queue creation is handled automatically when new connections
are initiated.
