All sites are queried one time in Edit Network page

Copied from https://core.trac.wordpress.org/ticket/38812

All sites are queried and shown in the red box when I visit Edit Network page. Generally, it's okay for small site, however, we have more than 14,000 sites in one network, and when I visit that page in our production, I broke down our Redis server. Please do the paging for it, thanks.

I'll likely fast-track this one into the next release. This is something I've spent a lot of time thinking about.

This UI has always been a compromise, frankly because WordPress doesn't offer a more intuitive one.

What about select2?

2.2.0 only comes with visual changes to this meta-box, nothing very functional has changed.

Putting this in the 3.0.0 milestone.
