Enable footer for the docs

[trsvchn]

Fixes #1649

Description:

I think the footer added here:

ignite/docs/source/_templates/layout.html

Line 251 in b1044d0

{% include "footer.html" %}

Moreover, "Built with Sphinx using a theme provided by Read the Docs." is hard coded in footer.html theme's template.

So, I think we can override footer.html with netlify badge.

Check list:

• New tests are added (if a new feature is added)
• New doc strings: description and/or example code are in RST format
• Documentation is updated (if required)

@trsvchn thanks for hacking it :) Looks good ! I wonder also if it could be difficult to set the badge on the same line as the copyright and "Built with Sphinx ..." ?

This is the result of footer tweaking.

Maybe we can do this with pure css. But it doesn't look simple to me.
