Subject: core: Major refactor of admin endpoint and config handling

Fixed several bugs and made other improvements. All config changes are
now mediated by the global config state manager. It used to be that
initial configs given at startup weren't tracked, so you could start
caddy with --config caddy.json and then do a GET /config/ and it would
return null. That is fixed, along with several other general flow/API
enhancements, with more to come.
