Previously, all caching of attribute values was done via the Attributes
object. However, some resource types override Resource.get_attribute() to
do custom handling of the trailing attribute path or dynamic attribute
names, and in these cases the resulting values were not cached (since they
don't go through the Attributes object).
This patch adds a caching step for these resources:
* OS::Senlin::Cluster
* OS::Heat::ResourceChain
* OS::Heat::ResourceGroup
* OS::Heat::AutoscalingGroup
* OS::Heat::SoftwareDeployment
* OS::Heat::SoftwareDeploymentGroup
* TemplateResource
* AWS::CloudFormation::Stack
