These commands ship in confluent_client/bin but had no .ronn man page, so
they did not appear in the generated documentation. Add man pages matching
the existing style, with synopsis and options taken from each command's
argument parser:
- confluent2ansible: export node inventory to an Ansible hosts file
- confluent2lxca: export nodes to a Lenovo XClarity Administrator bulk import CSV
- confluent2xcat: export nodes to an xCAT stanza definition (and optional macs.csv)
- dir2img: build a FAT image from a directory for nodemedia upload
- nodecertutil: manage BMC CA certificates and sign BMC certificates
- nodegrouprename: rename a node group
- noderename: rename nodes
