This is just to keep track of what we need to do in the short term.

• Mappings
• Configuration schemas for providers and provisioners
• Helper improvements around complex types perhaps
• Providers/AWS: aws_security_group needs an update func
• Providers/AWS: aws_eip needs an update func (re-assocation, I think this is possible in the AWS API). aws_eip also needs improved tests
