On python <3.4 the separator for json.dump() defaulted to (', ', ': ')
which may cause trailing whitespaces in rendered JSON files when used
with indent. This change sets the separator to (',', ': ') to prevent
trailing whitespaces with older versions of python.

This patch adds a new Heat software configuration hook that
can be used to generate Json config files in a composable manner
within Heat templates.
This can be useful for everything from providing data to ad-hoc
scripts from configuring kolla containers.
