form hope to add getAllFieldsName property

What problem does this feature solve?

dynamic this.props.form.setFieldsValue()

What does the proposed API look like?

const data = {.........};
const fields = this.props.form.getAllFieldsName();
const temp = {};
fields.forEach(item=>temp[item]=data[item]);
this.props.form.setFieldsValue(temp);

      const fields = Object.keys(this.props.form.getFieldsValue());
      const fieldsValue = {};
      fields.forEach(item => {
        fieldsValue[item] = getByIdRes.data[item];
      });
      this.props.form.setFieldsValue(fieldsValue);
