wiki: add getting started, scripting, registry and NBFT pages Add pages for topics the wiki only mentioned in passing: getting started with nvme-cli 3.x, the global options and nvme-cli.conf, using nvme-cli in scripts, the NVMe-oF ownership registry and exclusion list, and booting from NVMe-oF with NBFT. The commands were tested with nvme-cli 3.2 against a Linux nvmet target. Add the change of the default JSON output format version in 3.0 to the breaking changes, and link the new pages.
