JS keyup/keydown making user create very difficult to data entry in Horizon

[Paul Karikh]

On large datasets, when there are a lot elements to display on one page (>200 users on the page, for example) is could be very difficult to input data in the fors sicnce the page starts to freeze after any keypress. With 300 elements freezes are small and just annoying but after ~500 elements (500 users, for example) page freezes make form filling: there is a pause of 4-5 seconds after every character that has been entered.

There is also upstream bug about it: https://bugs.launchpad.net/horizon/+bug/1411892
