Share kernel Wireguard port with raw socket (#826)
This PR brings support of a shared port between stun (ICE agent) and
the kernel WireGuard

It implements a single port mode for execution with kernel WireGuard
interface using a raw socket listener.

BPF filters ensure that only STUN packets hit the NetBird userspace app

Removed a lot of the proxy logic and direct mode exchange.

Now we are doing an extra hole punch to the remote WireGuard 
port for best-effort cases and support to old client's direct mode.

Bind implementation (#779)
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 custom ice stdnet implementation (#754)
On Android, because of the hard SELinux policies can not list the
interfaces of the ICE package. Without it can not generate a host type
candidate. In this pull request, the list of interfaces comes via the Java
interface.

Fix connstate indication (#732)
Fix the status indication in the client service. The status of the
management server and the signal server was incorrect if the network
connection was broken. Basically the status update was not used by
the management and signal library.

Exchange proxy mode via signal (#727)
Before defining if we will use direct or proxy connection we will exchange a 
message with the other peer if the modes match we keep the decision 
from the shouldUseProxy function otherwise we skip using direct connection.

Report offline peers to agents (#728)
The peer login expiration ACL check introduced in #714
filters out peers that are expired and agents receive a network map 
without that expired peers.
However, the agents should see those peers in status "Disconnected".

This PR extends the Agent <-> Management protocol 
by introducing a new field OfflinePeers
that contain expired peers. Agents keep track of those and display 
then just in the Status response.

Use the conn state of peer on proper way (#717)
The ConnStatus is a custom type based on iota
like an enum. The problem was nowhere used to the
benefits of this implementation. All ConnStatus
instances has been compared with strings. I
suppose the reason to do it to avoid a circle
dependency. In this commit the separated status
package has been moved to peer package.

Handle peer interface config change (#348)
Before this change, NetBird Agent wasn't handling
peer interface configuration changes dynamically.
Also, remote peer configuration changes have
not been applied (e.g. AllowedIPs changed).
Not a very common cause, but still it should be handled.
Now, Agent reacts to PeerConfig changes sent from the
management service and restarts remote connections
if AllowedIps have been changed.

Fix error when removing peer conn (#264)
When stopping engine, all peer conns have to be closed
and for each peer WireGuard iface is called
to remove WireGuard peer.
This operation happens in a goroutine causing
Engine to remove the whole WireGuard interface before.
Therefore consequent calls to RemovePeer are unsuccessful.
This fix just adds a small delay before removing interface.

Support no-proxy mode connection mode (#245)
When one of the peers has a static public host IP
or both peers are in the same local network
we establish a direct Wireguard connection
bypassing proxy usage.
This helps reduce FD usage and improves
performance.
