metadata function got error because of wrong api url

[BlessingDev]

Since I got 404 error when call metadata function of Vimeo class, I looked into your code and vimeo api document. And I found out that the api url in your code is no longer valid.

The api url written in your code was http://vimeo.com/api/v2/video/{}.json. However, in document I could only find https://api.vimeo.com/videos/{video_id}.

I suggest you to change the code related to the api in next version.
