[SPDK] json conf file syntax

Hi,

I converted my old conf file using config_converter.py but there is no
Nvme section in the json file output. When I run nvmf_tgt I get these
errors.

Not sure why there is an iscsi_set_options method in my json.  This is
the nvme section in the conf file:

[Nvme]
  TransportId "trtype:PCIe traddr:0007:01:00.0" Nvme0
  HotplugEnable Yes
  HotplugPollRate 1000000

And my json is below. Is there something missing in it?
