When we used to allow cmd to be NULL, we had to hand the plugin
everywhere. We no longer do.
1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.
3. The init function takes a command, not a plugin.
4. Remove command_deprecated_in_nocmd_ok.

If the rpc plugin is run while an older version of reckless is found on
PATH, it produces an error:
2024-08-01T18:32:00.849Z DEBUG plugin-recklessrpc: reckless-stderr:usage: reckless [-h] [-d RECKLESS_DIR] [-l LIGHTNING] [-c CONF] [-r] [--network NETWORK] [-v]
{install,uninstall,search,enable,disable,source,help} ...
reckless: error: unrecognized arguments: --json
Catch this and don't try to parse the output as json.
This allows generic subcommands to be passed to reckless-rpc along with
the target to search/install/etc.. These commands are unvalidated so
far and may crash the reckless process.
Changelog-Added: reckless-rpc plugin: issue commands to reckless over rpc.
