A hook which helps write JSON files to disk for configuration or use with ad-hoc scripts. The data files are written to the named file location for each section listed under 'config'.

Multiple JSON files can be written out in this manner.

Example:

JsonConfig:

type: OS::Heat::StructuredConfig properties: group: json-file config: /tmp/foo: - bar - bar2

This would write out a JSON files at

/tmp/foo containing a JSON representation of ['bar', 'bar2'].
