[PATCH v2 2/2] docs/sphinx: change default role to "any"

[John Snow <jsnow@redhat.com>]

This interprets single-backtick syntax in all of our Sphinx docs as a
cross-reference to *something*, including Python symbols.

From here on out, new uses of `backticks` will cause a build failure if
the target cannot be referenced.
