Plugin documentation previously used ``.. list-plugins::`` for each
plugin command, which just produced the summary line. This might be
useful if there were also a link to the complete (per-project) docs for
the commands; but since we have the content available, we might as well
produce the complete plugin docs inline. That's going to be most useful
to a reader anyway.
So this commit switches from ``list-plugins`` to ``autoprogram-cliff``
-- except for the following, whose docs break the build when this is
done:
- octavia
- rsd
- trove
- zun
These fixups are tracked under task #37241 under this same story.

Once [1] fixed plugin doc generation, the (single) page it produced was
unusably huge. This commit splits it into one page per project.
Note that there are four plugin projects that didn't have sections
included:
- cue
- murano
- tripleo
- watcher
These were noted in hidden rst which is preserved in the (new) index
page.
