Provide default media name for Video media entities

I'll have a look into this. The biggest issue will be coming up with an automatic title from the available information. We don't have access to a video title based on the interface. The two bits of info we have that might be useful are the ID and the name of the provider. I'm thinking {{ provider }}: {{ id }} might work. This would produce titles like "YouTube: XgYu7-DQjDQ".

We would want to do it generically. Perhaps introduce a NamedVideoProviderInterface so that each provider has the chance to provide a name, then fall back to provider: id. I'll have a look at it, this week.

Part one, a default name in the media plugin. I know vimeo has a public oembed endpoint, but I'm not sure if the same is true for youtube. In any case, this makes it a bit nicer then the UUID.

An API based option for the Vimeo provider without breaking BC.

If this extends your existing interface then you'll only need to implement this one interface on the base class.

Fixed vimeo test.

Cleaned up some of the code and moved the { provider }: { id } logic into the plugin base. I believe this retains BC but I'm questioning if we actually have to. In every plugin I've encountered, it extends our base. Perhaps a BC break and a change record is enough?

Full patch.

Here is the BC breaking version.

Fixed broken vimeo handler.

And another one..

Should pass with a few alterations.
