There is only a single global g_nvmf_tgt that can be passed to this
function, so remove the parameter and use the global directly.

The section is really defining a subsystem as defined
by the NVMf specification. There does not appear to be
any need for a group of subsystems.
This change only updates the configuration file. It does
not remove all references to a subsystem group from
the code.

The specification refers to this concept as a Host,
so use that term. This only changes the configuration
file usage. Initiator groups are still referenced in
the code and will be removed later.

Previously, there was no way to determine what namespace ID was assigned
when a namespace was created via the NVMe library interface.
Also drop the incorrect comment about calling
spdk_nvme_ctrlr_process_admin_completions(), since
spdk_nvme_ctrlr_create_ns() checks the admin queue internally.

When recursively calling spdk_json_write_val() on another object or
array, the child call will handle printing out the whole
subobject/array, so the parent call should skip over all of its values.
Also fix the return value for the array/object case - if we get to the
end of the array or object, we should return 0 for success.

When using DPDK PCI support via VFIO, the PCI device is reset
immediately before calling the PCI driver's init function. In some
cases, the device seems to not be ready to handle MMIO accesses right
away. Until the cause of this issue is fully understood, add a 500 ms
sleep as a workaround.
