Public bug reported:

It would be nice if cloud-init query could give simple cli access to the
on-disk merged cloud-config.

Use cases that this would help:
  - customers wondering ultimately what default_user was used during cloud-init setup
  - simple CLI to view what config modules are configured active on a given boot
  - datasource configuration passed to cloud-init
  - network configuration passed to cloud-init

We sometimes get questions in IRC for non-ubuntu distributions or
unofficial images where our response is to look in /etc/cloud/cloud.cfg
and cloud.cfg.d to see what modules/users are configured. it'd be fairly
simple to instrument this in the existing cloud-init query CLI.

** Affects: cloud-init

- instance-data: surface default user in instance-data.json
+ instance-data: surface merged cloud-config in instance-data.json

** Summary changed:

- instance-data: surface merged cloud-config in instance-data.json
