We want to have non-amazon identifiers for the Heat resource types. These terms would be interchangeable in the template files, e.g. having `AWS::EC2::Instance` or `OS::Nova::Server` would produce the same result.
The original identifiers are in the form of `AWS::<product>::<resource>`. The list tries to use the OpenStack project and resource names where available.
This is the list of proposed names:
AWS::CloudFormation::Stack => OS::Heat::Stack AWS::CloudFormation::WaitCondition => OS::Heat::WaitCondition AWS::CloudFormation::WaitConditionHandle => OS::Heat::WaitConditionHandle AWS::CloudWatch::Alarm => OS::CloudWatch::Alarm AWS::EC2::EIP => OS::Nova::FloatingIP AWS::EC2::EIPAssociation => OS::Nova::FloatingIPAssociation AWS::EC2::Instance => OS::Nova::Server AWS::EC2::SecurityGroup => OS::Nova::SecurityGroup AWS::EC2::Volume => OS::Nova::Volume AWS::EC2::VolumeAttachment => OS::Nova::VolumeAttachment AWS::ElasticLoadBalancing::LoadBalancer => OS::ElasticLoadBalancing::LoadBalancer AWS::S3::Bucket => OS::Swift::Container AWS::IAM::User => OS::Keystone::User AWS::IAM::AccessKey => OS::Keystone::AccessKey HEAT::HA::Restarter => OS::Heat::Restarter AWS::AutoScaling::LaunchConfiguration => OS::AutoScaling::LaunchConfiguration AWS::AutoScaling::AutoScalingGroup => OS::AutoScaling::AutoScalingGroup AWS::AutoScaling::ScalingPolicy => OS::AutoScaling::ScalingPolicy AWS::RDS::DBInstance => OS::RDS::DBInstance
The mapping of resource types and Heat classes is in:
https://github.com/openstack/heat/blob/master/heat/engine/resources/register.py
Once we settle on the final names, we can just add the new entries into the `_resource_classes` dictionary.
