Add: a configurable delay before the popover is triggered

[benkoshy]

What is the PR?

• Adds a pause before the fetch action is triggered.

I hope this helps. I can add some documentation if required in another PR.

Why would we want to do that @benkoshy? 👍

On a page full of triggers, most would be needlessly triggered

[chakraskun]

+1 for this, just to avoid to trigger when user move the mouse around
