Improve get formValidationResult.fieldErrors

[nasdan]

When we are going to validate a form and we want to get fieldErrors, i.e in React, we have to :

(formValidationResult) => {
 const dataFormErrors: DataFormErrors = { ...this.state.dataFormErrors };

 formValidationResult.fieldErrors.forEach((fieldValidationResult) => {
   dataFormErrors[fieldValidationResult.key] = fieldValidationResult;
 });

 this.setState({
   ...this.state,
   dataFormErrors,
 });
}

We could create a method helper to encapsulate this mapping, something like :

Pseudocode:

const mapFieldValidationResults = (array: FieldValidationResult[]) => {
   const objectWithFields = { 
    [array[0].key] = array[0], 
    [array[1].key] = array[1],
     ..... 
   }

   return objectWithFields;
}

On future lc-form-validation versions we could return this "objectWithFields" directly on formValidationResult.fieldErrors

The scenario to cover:

• User has a form with some validations, these validations errors are not shown because we don't fire them til the user interacts with the inputs (touched).

• If the user click on the submit option, the validation form will be fired, but the error messages per field won't be updated.

We need an easy way to fullfill them.
