Allow for wait_for pass hash with options like send_cmd does

[vifreefly]

Currently it's not possible to pass options with wait_for command.
It will be nice to have this feature, because some of Chrome DevTools Protocol Events can accept options.

For example Page.frameStoppedLoading (can accept frameId option).

I just found that it's possible to pass block to the wait_for method:

client.wait_for do |event_name, event_params|
  event_name == "Page.lifecycleEvent" && event_params["name"] == "load"
end

So the problem solved :)
