cli: rework
* use plain json for argument format * rename feedback -> response to match code * reorganize args * tweak variable names to be more in line with miniconf and mqtt * use `mqtt` as broker * remove traces of stabilizer from script, rename to miniconf.py * add usage example * dual-iir/lockin-external: update broker address (for HITL), change mqtt path to convention
