Link to (some) plugin doc pages

We would like to use autoprogram-cliff to generate full docs inline for
each plugin. But for the following projects, that breaks the build:

- octavia
- rsd
- trove
- watcher
- zun

For those projects, we're using list-plugins instead, because that
builds, and it's better than nothing; but it only provides summaries of
the commands.

So with this commit, we add a link to the plugin documentation from the
actual plugin project where such documentation exists, which currently
is just:

- octavia
- watcher
- zun

(For rsd, I couldn't find openstack-published docs at all; for trove,
published docs exist, but the osc plugin isn't documented.)
