Configurable httpd init script
This PR aims to solve the feature request in:
The idea is a new inputfield is added to the server's Web config. This new field allows the user to optionally specify a custom apache init script. For example, if you install httpd24 from CentOS SCL, your systemd service is called
httpd24-httpd. If you add that here, the web_module will use that instead of the default. If you leave it empty (which is the default for new or upgrade installations) it falls back to the default behaviour of 'auto detecting' the init script.
