This PR adds supports for the WireGuard userspace implementation
using Bind interface from wireguard-go.
The newly introduced ICEBind struct implements Bind with UDPMux-based
structs from pion/ice to handle hole punching using ICE.
The core implementation was taken from StdBind of wireguard-go.
The result is a single WireGuard port that is used for host and server reflexive candidates.
Relay candidates are still handled separately and will be integrated in the following PRs.
ICEBind checks the incoming packets for being STUN or WireGuard ones
and routes them to UDPMux (to handle hole punching) or to WireGuard respectively.
* Add additional check for needed kernel modules
* Check if wireguard and tun modules are loaded
If modules are loaded return true, otherwise attempt to load them
* fix state check
* Add module function tests
* Add test execution in container
* run client package tests on docker
* add package comment to new file
* force entrypoint
* add --privileged flag
* clean only if tables where created
* run from within the directories
