Code Issues Proposed changes

Added pseudo param OS::project_id

Browse Source 
project id can be used to identify or tag which project the resources
belong to. The project id can be found in cfn pseudo param AWS::StackId, but when we
switch to hot, OS::stack_id is a pure stack id, no project info in it. So
we add OS::project_id to meet the similar scenario requirements.
