c-user: Use rubric for configuration options

Clear the page for each configuration options similar to the directives.

Use a rubric instead of a definition list for the application
configuration options similar to the directive documentation pages.  For
direcives and application configuration options use the same rubric
order.

Generalize value constraints to constraints.
