Hiera optimization: use a new hiera hook
This patch optimizes how we deploy hiera by using a new heat hook specifically designed to help compose hiera within heat templates. As part of this change: - we update all the 'hiera' software configurations to set the group to hiera instead of os-apply-config. - The new format uses JSON instead of YAML. The hook actually writes out the hiera JSON directly so no conversion takes place. Arrays, Strings, Booleans all stay in their native formats. As such we can avoid having to do many of the awkward string and list conversions in t-h-t to support the previous YAML formatting. - The new hook prefers JSON over YAML so upgrading users will have the new files prefered. (we will post a cleanup routine for the old files soon but this isn't a new behavior, JSON is now simply prefered.) - A lot of services required edits to account for default settings that worked in YAML that no longer work correctly in the native JSON format. In almost all these cases I think the resulting codes looks cleaner and is more explicit with regards to what is getting configured in hiera on the actual nodes.
