Feat fake dns address (#902)
Works only with userspace implementation:
1. Configure host to solve DNS requests via a fake DSN server address in the Netbird network.
2. Add to firewall catch rule for these DNS requests.
3. Resolve these DNS requests and respond by writing directly to wireguard device.

Feature/android route notification (#868)
Add new feature to notify the user when new client route has arrived.
Refactor the initial route handling. I move every route logic into the route
manager package.

* Add notification management for client rules
* Export the route notification for Android
* Compare the notification based on network range instead of id.

Fix incomplete verification URI issue in device auth flow (#838)
Adds functionality to support Identity Provider (IdP) managers 
that do not support a complete verification URI in the 
device authentication flow. 
In cases where the verification_uri_complete field is empty,
the user will be prompted with their user_code, 
and the verification_uri  field will be used as a fallback

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.

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.

Small code cleaning in the iface package. These changes necessary to

of the layer between WireGuard and business logic.
