Requests should return `Fog::Compute::Google::Operation`

[Temikus]

Currently requests return an API operation, i.e.: Google::Apis::ComputeV1::Operation:
And then usually get parsed by model like so:

operation = Fog::Compute::Google::Operations.new(:service => service)
                                                      .get(data.name)

That's a lot of duplicate (and sometimes inconsistent) code[1].

I propose to do the following:

• Write a helper method, e.g. Fog::Google.convert_operation that will contain the API -> Fog tanslation logic.
• For 2.0 replace all individual model logic with that method and make requests return Fog::Compute::Google::Operation

I would do deprecation in 2.0 and removal in 3.0 but I don't think we can mark it as deprecated somehow if people are using raw requests.

@icco WDYT?
