Form Component

[Benricheson101]

Description
It would be nice if there was a form component for sending multiple component inputs in a single payload. The way I envision this working would be to have a Form component that works similarly to the Action Row, where it has a component field that holds other components. When a user presses a button or makes a selection with a Select component or uses any other future component, instead of immediately sending a payload to the application, it would wait until a "Submit" button was pressed.

Why This is Needed
It would make it much easier to implement something like a form or a way of collecting multiple interactions to be processed all at once.

Having all component input returned in one payload instead individual payloads would prevent developers from having to use complex state-management/caching to store data between each payload.

Alternatives Considered
The developer could implement this themselves using an additional button component.

Additional Details
What I had in mind was something like this

-----------------------
| button 1 | button 2 |
|---------------------|
|   first dropdown    |
|---------------------|
|   second dropdown   |
|=====================|
|  submit  |  cancel  |
-----------------------

the Submit and Cancel buttons would be built-in to the Form component. Submit sends the payload and Cancel clears the input.

If this is added, I believe Text components to go along with the Form component would also be an interesting addition, as we would be able to have separate, labelled (as grayed-out text that appears when they are empty, for example) text fields without the need of multiple commands or prompts, and it would fit nicely within the proposed structure - the values in each text field would also be sent when 'Submit' is pressed. This would certainly be interesting to simplify bot setup and configuration commands, for example.

I also think a good idea would be radio (multi-choice) buttons would go nice with this. Which would be great for things like surveys, quizzes, etc.

This is (mostly) implemented to the tune of modals. Its not inline and doesn't support selects yet, but its there!
