Feature: add option to disable tooltips

### Description

Hi guys, I'm building new dashboards with dashboard 2 and so far looks very promising and beautiful. Thanks for doing great work, hope to be able to contribute as well.

I am deploying my dashboards to touch screens with enabled screen blanking and when I come back to tap the screen to wake up, I frequently tap a control that presents a tooltip. On the touch screen it does not look good (too small) and is hard to get rid of.

I'd prefer an option to disable the tooltip, or have the ability to override it with incoming `msg` so that I can disable it when not needed...

Not sure if the functionality is already available, did not find it in the docs.

If you point me in the right direction, I'd love to open a PR to address this.
Thanks Martin
