Zane Bitter e5707618f3 Avoid always loading nested stack on update 
Previously, when calling StackResource._validate_nested_resources() (which
we do whenever we create or update a nested stack), we would load the
nested stack into memory to validate the number of resources in the nested
stack, unless the max_resources_per_stack config option was set to -1. This
meant we would load the nested stack into memory in the same engine as the
parent on every update.

To reduce the memory high-water mark, fetch the information we need over
RPC from another engine instead.

To ensure this is only called once, move the call into the validate code.
(Previously it was called again in the create/update itself.)

Heat

Heat is a service to orchestrate multiple composite cloud applications using templates, through both an OpenStack-native REST API and a CloudFormation-compatible Query API.

Why heat? It makes the clouds rise and keeps them there.

If you'd like to run from the master branch, you can clone the git repo:

git clone https://git.openstack.org/openstack/heat

Python client
