We need getSelfAWSInstance to be working anyway; we might as well build
it early, and then we can use its methods to extract e.g. the VPC ID

Now that we can't build an awsInstance from metadata, because of the
PrivateDnsName issue, we might as well simplify the arguments.

Create a 'placeholder' method though - newAWSInstanceFromMetadata - that
documents the desire to use metadata, shows how we would get it, but
links to the bug which explains why we can't use it.
