fix(nvmf): support /etc/nvme/config.json

Since nvme-cli 2.0, configuration of subsystems to connect to is
stored under `/etc/nvme` in either `discovery.conf` or `config.json`.
Attempt discovery also if the latter exists, but not the former.
Also, install "config.json" if it's present on the root FS.

As before, "rd.nvmf.discover=fc,auto" will force either file to be ignored,
and NBFT-defined targets take precedence if found.
