[RHOSC] Create a common component for local development #966

RESERVED FOR RHOSC

Scope: All mappers

Description

Each mapper package has now a different local development playground. (yarn start in a package repository) A lot of schemas are duplicated.

We should introduce a common component that will be used in all mappers and will:

• use shared schemas
• use component design from each design libraries (for buttons, select)
• remember form & playground state when page is refreshed
• allow to write a custom schema
