A hook which helps write hiera files to disk and creates the hiera.yaml to order them. This is typically used alongside of the puppet hook to generate Hiera in a more composable manner.

Example:

ComputeConfig:

type: OS::Heat::StructuredConfig properties: group: hiera config: hierarchy: - compute datafiles: compute: debug: true db_connection: foo:/bar # customized hiera goes here...

This would write out:

1. An /etc/hiera.yaml config file with compute in the hierarchy.
2. An /etc/puppet/hieradata/compute.json file loaded with the custom hiera data.
