Comment 1 for bug 1851428

I'm not sure this is the right place, but since release 19.3, the list of modules has disappeared from the documentation sidebar.

- version 19.3: https://cloudinit.readthedocs.io/en/19.3/topics/modules.html
- version 19.2: https://cloudinit.readthedocs.io/en/19.2/topics/modules.html

In 19.2, the sidebar has an entry for each module, and it's a lot easier to find and navigate to appropriate module.
