Allow for additional reverse proxy vhost options

the class foreman_proxy_content::reverse_proxy already has a parameter vhost_params.
However, it is not exposed for usage, so while one can specify additional vhost
parameters for HTTP via pulpcore::apache::http_vhost_options, there is no
way to do the same for HTTPS. This commit changes that by adding a variable
foreman_proxy_content::reverse_proxy_vhost_params that is then passed on to
foreman_proxy_content::reverse_proxy such that a user can add additional vhost
parameters for HTTP and HTTPS e.g. via custom-hiera.
