json or KDL config editing support (experimental thing.)

[petersilva]

when a flow's configuration is resolved... it could be written as .config/sr3/comp/config/configuration.json
and we could have a json schema file written to .config/sr3/configuration_schema.json

with the two could have a structured editing of configs using a WYSIWIG editor...

• pyjsoneditor
• https://panel.holoviz.org/reference/widgets/JSONEditor.html (is this using the above? not sure.)

anyways... the schema can constrain the values, e.g. for set types to have choices.

Of course... this is kind of one way... once you start editing in json, you can't get back to the input config format.
dunno... might be a fun student project.

This becomes more helpful because the current syntax does not express scope at all, and in upcoming changes... aka multibroker/multi-queue support, the scope of many settings changes. (#35 ... some more...)

Also enables future GUIs...

found KDL config file format, and I think it's better for humans than JSON...

The syntax is nicer.
