Storybook: Knobs don't update when the dropdown option are generated dynamically.

[javidhsueh]

Describe the bug
I have two knobs, text input and select. The text input is for accepting a json object. The select dropdown will generate options dynamically according to the data input. However, the select doesn't update at all

To Reproduce
Steps to reproduce the behavior:

1. Create two knowbs, "text" and "select"
2. Enter a json object with many properties.
3. Parse the json object from "text input" and generate options per attribute
4. Pass the new options into "select" input

Expected behavior
The dropdown should update with new options

[examples.BASIC_EXAMPLE]: function Story1() {
  const groupDataInput = 'Data input';
  const customizations = 'customizations';
  const newData = object('Data', complexMock, groupDataInput);
  const options = extractDataOptions(newData[0]);
  const sizeControl = select(
    'Size control', options, customizations
  );
  return (
    <MyComponent
      data={newData}
      sizeControl={sizeControl}
    />
  );
},

I came across a mostly similar issue trying to load fake data for a select with the fetch API. I believe a solution to this issue would also solve my problem.

@ardouglass hi! I stumbled upon this issue too, as I'm trying to update one knob based on another.

Something that seems like it could hep in my case, and possibly yours and @javidhsueh's (perhaps) is a combination of this: https://github.com/storybooks/storybook/pull/3909 and using forceReRender.

Currently it looks like the select() knob on its own doesn't allow too much in the way of dynamic updates.
