Hi Andrey, Thank you for the email.
One question: As I spoke with our OpenStack experts today, I was never faced with a notion such as Heat Template (Heat Attack), they only mentioned FLAVOUR. I am not personally sure heat templates exist in OpenStack, so will need to follow up on this. For Flavours a certain set of params can be retrieved. Let me know if there are any other questions. Kind Regards, Dmitry.
