issue/1350 [doc] add other key to options hash
[ecloud|compute] Fixes missing value

`:connection` key was not paired with a value. Initializer just accepts
options hash as I read it so assume this was an oversight.

Create snapshot
Updated default Rackspace Compute provider to return a Fog::Compute::RackspaceV2 instance. In order to access legacy Cloud Servers, a :version => :v1 parameter will need be passed like so Fog::Compute.new({
  :provider                 => 'Rackspace',
  :rackspace_username        => USER,
  :rackspace_api_key    => API_KEY,
  :version => :v1
})
