Add pagination to the binaries list

[saraycp]

Some packages have a huge list of binaries on https://github.com/openSUSE/open-build-service/blob/e0d7a709fa2973bbf611888bec7d676afc872985/src/api/app/views/webui/packages/binaries/index.html.haml

open-build-service/src/api/app/controllers/webui/packages/binaries_controller.rb

Line 28 in 7180eaa

def index

Let's add pagination. UI-wise it makes no sense to have such long list at a glance, and it might also help with performance.

@saraycp can you please mention how much binaries should rendered per page ?
