LF Docs Config

The purpose of this project is to allow LF projects a centralized location for storing common project configuration.

To use this a project should create a conf.yaml file in the same directory as their conf.py. The minimal configuration for conf.py is:

from docs_conf import *

The minimal configuration for conf.yaml file is:

---
project_cfg=myproject

Docs will load default configuration for 'myproject' from this package if it exists, otherwise it will load basic configuration from Sphinx defaults.

Configuration precedence for configuration is as follows:

conf.py structure and documentation:: http://www.sphinx-doc.org/en/stable/config.html

TODO

[ ] Define the minimal set of config values to release initial version.

These can probably come from ODL/OPNFV site conf.py files.
[ ] Use sane defaults, and don't error out if something is not set.

We must import each config cleanly (if it doesn't exist, set None or something; like the function dict.get()).
[ ] Create own documentation for project detailing use of 'conf.cfg'

file as some values will require subkeys given that they're dictionaries or expect a list of tuples.
[ ] Setup and document section. With the documentation organized by section,
the config should also contain these section and look for their values under them.

Sections:
- general (aka sphinx)
- project
- i18n
- html_output
- apple_help
- epub_output
- latex_output
- text_output
- manpage_output
- texinfo_output
- linkcheck
- xml
- cplusplus
[ ] Configure pre-plugin sections, and reference by plugin listing.
