Support typical input field aspects such as tabIndex

[mschipperheyn]

I'm running into an issue where I'm hiding a dateinput field by hiding it off-screen using position absolute.

This creates problems when someone hits the tab to cycle through form inputs, bc when you hit the date input field, it opens the calendar, which causes all sorts of havoc in the ui.

In general terms, input field aspects such as tabIndex, ariaLabel etc should be configurable on the api. It prob doesn't make sense for all properties given the heavy ui customization that this component effectuates, but tabIndex is definitely one of them, not just because of my slightly unique use case.
