Instead of using shell commands, use python to parse the output
of lspci. This is considered more "Pythonic".

Previously, if spdk_rpc_setup() returned early due to the RPC service
being disabled in the configuration file, it would leave itself
registered as a poller and continue to run for the life of the app.

The shared memory pool for a session is associated with
a particular RNIC via the protection domain. New connections
attempting to join a session that came in on a different RNIC
can't use that memory, so must be rejected.

Use the lower level registration functions. The RDMA-CM
examples use the ibv_* versions, so who knows if the
rdma_reg_* wrappers are even well tested.

A status member of spdk_bdev_io structure is set after the if block.
Therefore a status parameter should be checked instead of a status

The value of CAP should not change during the lifetime of a controller,
so read it once during ctrlr_construct and store it in the ctrlr.

Rather than embedding adminq directly in the spdk_nvme_ctrlr structure,
change it to a pointer to a spdk_nvme_qpair. This is necessary to allow
the transport to extend the qpair structure.

Previously, we directly assigned the pointer of pool_name
and rbd_name, and this is not safe. After the rpc test,
we found the string value is not correct, so use strdup.

This requires a couple of related changes:
- I/O queue IDs are now allocated by using a bit array of free queue IDs
instead of keeping an array of pre-initialized qpair structures.
- The "create I/O qpair" function has been split into two: one to create
the queue pair at startup, and one to reinitialize an existing qpair
structure after a reset.
