Swap to fog-aws

[bdwyertech]

We don't need all of Fog, only the AWS portion of it.

This should resolve #539

Additionally, removed weird logic for finding ~/.aws/config profile

Hotfix

Gem file available on my fork's release page
Just do a vagrant plugin install ~/PATH/TO/vagrant-aws-0.8.0.gem

Ping! Can we get this merged?
