Autocomplete attribute for rux-input

[micahjones13]

Requested Feature: Autocomplete attribute on rux-input

Why this needs to be added

The ability to add this attribute would make form submissions easier on users and enable the use of password managers to auto-fill inputs.

More Context

This was previously an attribute, but wasn't actually working as intended due to a hidden input that we render to allow for use in native form elements - see more info on that in this article.

So far we've learned that the autocomplete attribute will not work as long as there is a hidden input rendered as well. We're looking at making rux-input a scoped shadow dom'd component to get around this issue in the future.

Updates / Progress

Because this attribute wasn't working, it was removed as part of #881.
A ticket has been created to look into making rux-input a scoped shadow dom component.
