Make mod_* classes parametrized.

Add parameters $options and $directives to the mod_ssl, mod_perl and
mod_wsgi classes.  This allows users to specify options and directives
to the modules without having to introduce extra classes inheriting
our mod_* classes and overriding the apache::module::globalconfig
declarations we have.

This seems to be somewhat more in line with current thinking in the
Puppet community as well.
