Input group - rework to better support flexible children
Created by: mcoker
^ is a narrow/specific scope and not necessarily the best way to style the elements in the input group. Instead of styling specific components, we should likely have structural input group elements that handle the spacing/styling if we can.
A pf-c-input-group__item
element would be more consistent with other "group" components/elements, and would help us with spacing, focus management, would give us the ability to introduce variations, control item size, etc.
