Following work on reorganising the requires, there was an inconsistent
approach to where service wrappers are required. (Fog::Compute...)
Since they should be standardised and shared across providers (although
they really aren't yet) they have been moved to `fog-core` gem.
Each provider has their own `lib/fog/{provider}/core` files that is
required by each of their services. These files should all require
`fog/core` which already required most or these.
So this removes the extra cases to concentrate them in core.
Should facilitate the following:
require 'fog/aws'
require 'fog/compute'
require 'fog/aws/compute'
I think once you `require 'rubygems'` those should work.
further cleanup should reduce common requires (ie nokogiri)
