class Fog::OpenStack::OrchestrationUtil::RecursiveHotFileLoader

Resolve get_file resources found in a HOT template populating

a files Hash conforming to Heat Specs
https://developer.openstack.org/api-ref/orchestration/v1/index.html?expanded=create-stack-detail#stacks

Files present in :files are not processed further. The others

are added to the Hash. This behavior is the same implemented in openstack-infra/shade
see https://github.com/openstack-infra/shade/blob/1d16f64fbf376a956cafed1b3edd8e51ccc16f2c/shade/openstackcloud.py#L1200

This implementation just process nested templates but not resource

registries.
