Use standard parameter description format for wsgi::apache

Currently parameter description of the <module>::wsgi::apache classes
are formatted differently in individual modules, and this is making
the maintenance effort quite difficult.

This change updates the description format following the srandard one
we are globally using in our modules to reduce undesired differences
between modules.
