Chad Smith has proposed merging ~chad.smith/cloud-init:schema-autodoc into
cloud-init:master.
Commit message:
docs: Automatically generate module docs form schema attribute if present
We have started adding jsonschema defintions for cloudconfig modules (cc_ntp).
This branch allows us render sphinx docs using the module's shema definition
instead of using the module's docstring.
It allows us to generate our module documentation directly from the schema
definition and avoid duplicating that documentation in the module-level
docstring. The corresponding module documentation is extended a bit to
differentiate between config schema and potential examples.

To test:
tox -e docs
xdg-open doc/rtd_html/topics/modules.html # look over the cc_ntp module
# merge this branch and remove part of the module docstring
cloudinit/config/cc_ntp.py
xdg-open doc/rtd_html/topics/modules.html # to view the differences in
styling and content of cc_ntp
