Clean up direct dependencies on puppetlabs-apache

This change removes direct reference to some classes in
puppetlabs-apache. Details are explained below.

- The api class doesn't need access to anything defined in
  apache::params

- The following classes are included by the openstacklib::wsgi::apache
  resource type, and current inclusions are just redundant.
