(refactor) Validation onChange & onBlur only for field, and onSubmit for form

[carere]

This PR remove the globals validators from all the Form in the app (except for the onSubmit).
The removed validators are now assigned to each form's field.

I'm arriving after the merge but naively this looks pretty verbose - is there any more "shorthand" way of handling this ?

Is there a reason why all the validators have been moving to field level? I can't understand why we would want to have so much boilerplate per field.
When I tested it, just removing the onBlur form validation was working (if you have an onChange validation the onBlur is pretty much useless)

@ChibiBlasphem the problem is that when you specify validators on the form, they validate ALL the form, if ANY fields "change" or "blur".
By specifying those validators on field level, you prevent one field "onChange" to trigger the form "onChange", and then validate the all form :)

Ok I get it. It's a little verbose so I think we will eventually create an abstraction to manage this more nicely.
