Current behavior

In 5.x version AbstractControlOptions has been added as parameter to FormControl constructor. FormBuilder#control() method should create new control by provided configuration. Currently signature/input parameters do not match FormControl.

Expected behavior

control(
     formState: any = null,
      validatorOrOpts?: ValidatorFn|ValidatorFn[]|AbstractControlOptions|null,
      asyncValidator?: AsyncValidatorFn|AsyncValidatorFn[]|null
): FormControl {
    return new FormControl(formState, validatorOrOpts, asyncValidator);
  }

Minimal reproduction of the problem with instructions

this.fb.group({
    "input1": this.fb.control('', {updateOn: 'submit'})
});

What is the motivation / use case for changing the behavior?

Just to keep code consistent

Environment

Angular version: 5.0.0-beta6

Other

It would be nice, if you could also update FormBuilder#group() to support AbstractControlOptions when simple json is provided.
