The Service object now offers handling services on a system level,
and gathering information whether it's enabled or running.
New methods: enable, disable, is_enabled, is_running;
For this it needs the correct (system-level) service name.
All of the methods can be overridden/customized.
This changes all modules to the new Service object and deletes
action scripts that are not required anymore.
- Authentication using client certificates. Extra password based
authentication for later.
- Auto setup of CA, server and client certificates.
- Provides a .ovpn profile for each user for easy setup.
- Use 4096 bit Diffie-Hellman parameters for better security. If this
takes to much time, reduce it to 2048 or 1024, at least during
debugging.
