cmdeploy: replace globals() subcommand scan with explicit SUBCOMMANDS list

The get_parser() loop that scanned globals() for *_cmd names was fragile
and forced # noqa: F401 on all lxc imports (ruff couldn't see they were
used dynamically).

Replace it with an explicit SUBCOMMANDS list of
(cmd_func, options_func, needs_config) tuples.  This makes the full set
of subcommands visible at a glance, their registration order defined,
and the imports unconditionally used (no more noqa suppressions).
