[Uptime] Typeahead search updates the content for every character entered

[formgeist]

Summary

I was trying out the new typeahead search for monitors in Uptime, but I found that the experience a little jarring as the typeahead updates the page content for every character immediately. I would like to suggest that we add a small delay to avoid the slowed-down typing experience and optionally only update the content on submit (the user will need to hit enter to confirm their search). I also imagine it's firing a request for every single keyword entered which seems wasteful.
