- add `inputSchema` column in serverless function. This is an array of
parameters, with their name and type
- on serverless function id update, get the `inputSchema` + store empty
settings in step
- from step settings, build the form
TODO in next PR:
- use field type to decide what kind of form should be printed
- have a strategy to handle object as input
