Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>

ovpnmain.cgi: Restart instead of reload

The option to reload the server does not seem to work well. The running
is process is performing a number of checks that make very little sense
and PID files get written by the user that launches the process (i.e.
root) instead of the user that the process is running as later on (i.e.
nobody). Since there is no chance to keep any existing connections alive
this way, we may just as well restart the service for now.

it in a ZIP container.

Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>

ovpnmain.cgi: Include the PKCS12 certificate on config export

Before, OpenVPN did not support PKCS12 files in an embedded format. We
extracted the key and the certificate in PEM format instead.

This is no longer necessary and therefore we can simply include the
file.

For dynamic pools, this change is easy and does not require any extra
