7ef5d754f7 docs: ARC: Improve readability
There were some things which made rendered document
look not very elegant. That was because:

1. Numbered lists were formatted in more of Markdown way
   rather than true reStructuredText and so were displayed
   as a plain text with leading numbers.

   Well, moreover numbered lists were not needed as in all cases
   we were just listing a couple of options w/o any intention to
   follow any particular order, so a simpler unordered list fits
   better and looks cleaner.

2. URL's of external resources were added as they are
   (which is OK in a plain text, but make not much sense in
   a HTML where we may use more human-friendly link names
   with URL's hidden.

3. Some URL's had trailing slashes which were not really needed

Fix all items from above!

a6fb8b5acf docs: add support for RTD dark mode
This is actually an overlay on the top of the RTD theme, which
requires to include first the RTD theme.

It should be noticed that, when the dark theme is used, the
DOCS_CSS files won't be the last CSS themes. So, it won't
override the dark.css style by default. So, it is needed
to force the them override with "!important".

This small script, for instance, produces a nice output with
the RTD dark theme:

	DOCS_THEME=sphinx_rtd_dark_mode
	cat << EOF > dark_override.css
	  html body {
	    font-family: arial,helvetica,sans-serif;
	  }
	  html[data-theme='dark'] body {
	    color: white !important;
	  }
	  html[data-theme='dark'] .sig-name {
	    color: green !important;
	  }
	  html[data-theme='dark'] .wy-menu-vertical a {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h1, html[data-theme="dark"] h2, html[data-theme="dark"] h3 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h4, html[data-theme="dark"] h5, html[data-theme="dark"] h6 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] h7, html[data-theme="dark"] h8, html[data-theme="dark"] h9 {
	    color: #ffcc00 !important;
	  }
	  html[data-theme="dark"] .wy-nav-content a, html[data-theme="dark"] .wy-nav-content a:visited {
	    color: #ffcc00 !important;
	  }
	EOF

fca7216bf5 docs: allow selecting a Sphinx theme
Instead of having RTD as an almost mandatory theme, allow the
user to select other themes via DOCS_THEME environment var.

There's a catch, though: as the current theme override logic is
dependent of the RTD theme, we need to move the code which
adds the CSS overrides to be inside the RTD theme logic.

Fixing it with the simples set of docs now:
1. Overview with pointers to other informational resources
2. Autogenerated feature table

Note though it's just the very beginning, there will be more
for sure given time as there're many things worth documenting
and in fact even contents itself is avaialble but just spread
in some other places. Now we'll try to keep all here and
then maintain it looking forward to match the state of development.

5c81691bb6 docs: admin-guide/blockdev: Remove digraph of node-states
While node-states-8.dot has two digraphs, the dot(1) command can
not properly handle multiple graphs in a DOT file and the
kernel-doc page at

    https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html

fails to render the graphs.

It turned out that the digraph of node_states can be removed.

Quote from Joel's reflection:

    On reflection, the digraph node_states can be removed entirely.
    It is too basic to contain any useful information. In addition
    it references "ioctl_set_state". The ioctl configuration
    interface for DRBD has long been removed. In fact, it was never
    in the upstream version of DRBD.

Remove node_states and rename the DOT file peer_states-8.dot.

d69dab7de2 docs: conf.py: fix support for Readthedocs v 1.0.0
As described at:
	https://stackoverflow.com/questions/23211695/modifying-content-width-of-the-sphinx-theme-read-the-docs

since Sphinx 1.8, the standard way to setup a custom theme is
to use html_css_files. While using html_context is OK with RTD
0.5.2, it doesn't work with 1.0.0, causing the theme to not load,
producing a very weird html.

Tested with:
	- Sphinx 1.7.9 + sphinx-rtd-theme 0.5.2
	- Sphinx 2.4.4 + sphinx-rtd-theme 0.5.2
	- Sphinx 2.4.4 + sphinx-rtd-theme 1.0.0
	- Sphinx 4.3.0 + sphinx-rtd-theme 1.0.0
