Authorization

Use Ferrum's network.authorize to set credentials for HTTP basic authentication. It intercepts requests, so the block decides what happens to every request and has to continue it:

page.driver.browser.network.authorize(user: "login", password: "pass") do |request, _index, _total|
  request.continue
end
visit "/admin"

Keep all three block arguments. With one, RuboCop's Style/SymbolProc turns the block into &:continue, which raises ArgumentError because Ferrum passes three.

Credentials are cleared at the end of every test.

page.driver.authorize(user, password) and page.driver.basic_authorize are deprecated in favor of it.
