Fix python-openstackclient plugin doc build3.1.0

Some plugin command option help strings were using invalid syntax to
refer to another option. This looked odd in CLI output

  --marker <ID>         Begin displaying the results for IDs greater than
                        thespecified marker. When used with :option:`--limit,`
                        setthis to the last ID displayed in the previous run.

and also caused building autoprogram-cliff from python-openstackclient
to break with errors like:

<ListDatabaseInstances>:1:unknown option: --limit,

This commit reformats the help strings to use double backticks, which
render sanely in the CLI help and also build properly from
python-openstackclient.
