Traffic via newly added client won't pass through until firewall is reloaded.
Unfortunately it isn't triggered by network restart, so we have to make sure it happens.

Reloading firewall after removal of client on the other hand
seems to work fine most of the time, but still it isn't triggered by network restart reliably.
So this will force reload after removing vpn client as well.

Make flake8 happy :-)

Interface name has length limit we need to adhere to. Therefore cutting
the end of the VPN id.
