Handle reconnect after system goes into sleep/hibernate

Let's first check and reproduce the problem:

1. have the OpenVPN turned on
2. hibernate/sleep
3. wake up -> OpenVPN does not work, but internet traffic is blocked

It takes some time until OpenVPN notices and restarts... This makes sense for TCP (as the TCP connection is gone). But I don't know why this behaviour also affects UDP connections.

Things to discuss:

• do wee need it?
• Why has nobody complained about so far?
• how to handle it (os, linux distro)?
