cubicweb-jsonschema #17073912 Use a dedicated uicfg-like configuration mechanism [validation pending]

We should avoid using existing uicfg definition to format JSON Schemas because this appears not very practicable from client point of view.

Instead, we should have a dedicated configuration mechanism (probably based on cubicweb.rtags to have a declarative way - close to schema definition).
