[config] first cut of config rewritten in golang

still to do:
* Rework disk format to be okay with quotes
* Fix Dockerfile deployments
* Dedup code in the subcommands
* Add --encode
* Add deploytests for the new stuff
* Restore some log messages (should I make some helpers in common?)
* Restore some functions that may be used by 3d-party plugins
