heat-jeos : convert cfn-hup to use CloudFormation API
heat-jeos : convert cfn-hup to use CloudFormation API

Covert cfn-hup to read resource metadata via the heat CloudFormation API
We use the boto client library, which simplifies client connection to the
API.

Note this means all instances using cfn-hup must now
create /etc/boto.cfg and /etc/cfn/cfn-credentials (populated with keys
from AWS::IAM::User and AWS::IAM::AccessKey), see HA template for
example.

Fixes #25
