Upgrade to Compute Engine Beta API

[stephenplusplus]

It looks like a new GCE API is coming to town: https://cloud.google.com/compute/docs/reference/beta/

@jgeewax should we move our support from v1 to beta?

It should be on the list of stuff for us to do, yep. I'll let @omaray decide the priority, but my vote is "not very important" right now due to the impending ability to auto-generate (and the fact that this surface is enormous....)

[stephenplusplus]

Sounds good. We had a feature request come up that is solved in the beta (#1470)... is it okay to gradually introduce support for the beta API, or best to do it all at once?

[jgeewax]

That's tricky. I'd recommend avoiding a mix-and-match approach as it makes things complicated (what if someone wants to enable the old API but isn't OK with enabling features in another -- I don't want our answer to be "it works but you have to enable the Beta API!")

[omaray]

Yes, Compute is not high priority right now. I need to confirm a couple of items before we can auto-generate the whole surface - but that's the end goal. Stay tuned.
