	On cloud-init upgrade path from 18.3 to 18.4 cloud-init changed how instance-data is written. Cloud-init changes instance-data.json from root read-only to redacted world-readable content, and provided a separate unredacted instance-data-sensitive.json which is read-only root. Since instance-data is only rewritten from cache on reboot, the query and render tools needed fallback to use the 'old' instance-data.json if the new sensitive file isn't yet present. This avoids error messages from tools about an absebt /run/instance-data-sensitive.json file. LP: #1798189
2018-09-11	user-data: jinja template to render instance-data.json in cloud-config	Chad Smith
	Allow users to provide '## template: jinja' as the first line or their #cloud-config or custom script user-data parts. When this header exists, the cloud-config or script will be rendered as a jinja template. All instance metadata keys and values present in /run/cloud-init/instance-data.json will be available as jinja variables for the template. This means any cloud-config module or script can reference any standardized instance data in templates and scripts. Additionally, any standardized instance-data.json keys scoped below a '<v#>' key will be promoted as a top-level key for ease of reference in templates. This means that '{{ local_hostname }}' is the same as using the latest '{{ v#.local_hostname }}'. Since instance-data is written to /run/cloud-init/instance-data.json, make sure it is persisted across reboots when the cached datasource opject is reloaded. LP: #1791781
