[PATCH v2 23/79] docs: netlabel: convert docs to ReST and rename to *.rst

[Mauro Carvalho Chehab <mchehab+samsung@kernel.org>]

Convert netlabel documentation to ReST.

This was trivial: just add proper title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
