Allow the use of fog options from .fog file

[locochris]

ie. remove all the validations and just let fog worry about it
(which BTW it does)

[locochris]

NB. This also allows the use of rackspace_cdn_ssl: true from the ~/.fog file so asset_host can be set to use the correct public_url otherwise it will use the non-ssl public_url.

eg. in rails config/application.rb

# Set assets host
require 'asset_sync'
config.action_controller.asset_host = AssetSync.storage.bucket.public_url if AssetSync.enabled?

Plus the rackspace_servicenet: true option in ~/.fog (to allow connecting to Rackspace cloudfiles over internal IP addresses, which is apparently faster and free).

Not sure about this yet, but can you please rebase off of master, hopefully build will then be passing and we can look further at getting merged in

[locochris]

Rebased.

I'll let you decide whether or not its your concern to validate parameters that you pass to an external library.
My only requirement is that I need some way of passing these extra options on to fog.
(ie. rackspace_cdn_ssl and rackspace_servicenet)
